 FeCrAl 145 is a ferritic iron-chromium-aluminium alloy (Cr content is around 23%) with high resistivity and very good oxidation resistance suitable for temperature applications up to 1400°C. This alloy has a better life time in sulfur atmospheres than nickel-chromium alloys. ed for electric furnaces in ceramic,FeCrAl 145 is speci chemical and metallurgic industries, and for all applications where it is necessary to apply a very high temperature of use.

Advantages of FeCrAl compared with NiCr: 

  • A higher resistivity (until 1.44 ohm mm²/m).
  • A temperature of use higher in the air (1300°C against 1200 °C for Resistohm 80).
  • A higher charge rate.
  • A good resistance to sulphurous and carbonaceous atmospheres.
  • A lower density which means: with an equal weight of material a more important number of elements.

Unalloyed, hard-rolled steel, mat. no. 1.0338 (DC04)
Unalloyed steels are very cost-effective materials for simple parts that don’t need to be corrosion-resistant and are not subjected to mechanical strains. With a tensile strength of at least 590 N/mm² (+C590), the products stocked at h+s are easy to blank but can only be dished or deep-drawn to a limited extent. Due to thickness tolerances according to EN 10 140, this material is only suitable for shim parts that do not have high precision requirements.
Unhardened, hardenable spring steel strip, mat. no. 1.1248
With a carbon content of 0.75%, material 1.1248 is frequently used as an alloy for springs. In an unhardened state, this steel is very easy to stamp and form; however, it must then be hardened to achieve a high tensile strength and hardness.
Hardened spring steel strip, mat. no. 1.1274
With a carbon content of over 1%, this material is very well suited for feeler gauge strips and precision foils as well as highly stressed springs that are not subject to any corrosion requirements. In particularly igh-quality designs, as the only carbon steel, 1.1274 is suitable for shock absorbers and flapper valves.
Hardened tool steel, mat. no. 1.2003
The addition of a small amount of chromium gives this material high wear-resistance and a better through-hardening in large cross-sections. With a Rockwell hardness of 47–51 HRC, this material is also suitable for smaller tools.
Hardened, rust-resistant special spring steel strip 1.4031 (AISI 420)
As a result of the alloying with 13% chrome and 1% molybdenum, this alloy is corrosion-resistant against damp air, water vapour and water, but is not sufficiently resistant to chloride ions and acids. The advantages of this steel lie in its good wear-resistance and minimum internal tensions. With a tensile strength of 1700–1950 N/mm2, this material is ideal for springs, gauges, tools and knives. In a particularly high-quality design, this material is also suitable for flapper valves.
Hardened, stainless tool steel, mat. no. 1.4034 (1.2083) As a result of the alloying with 13% chromium, this martensitic chrome steel is corrosion-resistant against damp air, water vapour and water, but is not sufficiently resistant to chloride ions and acids. This material has a lower corrosion-resistance compared to 1.4310. The advantages of this steel lie in its good wear-resistance and minimum internal tensions. With a Rockwell hardness of 50–54 HRc, this material is ideal for gauges, tools and machine cutting tools in the food industry and scalpels. Materials 1.4034 and 1.2083 are only marginally different in terms of carbon content.
Cold-rolled, stainless spring steel strip, mat. no. 1.4310
As a result of the alloying with 17% chrome and 7% nickel, this material is particularly corrosion-resistant. Cold-rolling gives this material a high tensile strength. It has a significantly higher strength than 1.4301. As a result, material 1.4310 is very well suited for stainless-steel precision gauge strips and precision foils. This material is only weakly magnetic and therefore cannot be held in place on magnetic clamping plates during grinding. When chamfering or bending material 1.4310, please be aware that folds should always run transversely to the roll direction. The roll direction must also be observed when using the material as a flat spring.
Stainless precision steel strip 1.4404
Due to its higher content of nickel and molybdenum, this material is significantly more resistant to corrosion than 1.4301 or 1.4310. In an annealed state, this material has very good deep-drawing properties due to the high nickel content. In a hard-rolled state, this material can be used for springs in corrosive environments. Similarly to 1.4310, 1.4404 becomes slightly magnetisable as a result of hard-rolling; however, due to its higher nickel content, its magnetism is less than in 1.4310.
Heat-resistant ferritic chrome steel, mat. no. 1.4767
By adding approximately 6% aluminium and traces of yttrium and hafnium, this ferritic steel is incredibly heat-resistant up to 1200°C. We stock this material in a hard-rolled state but it becomes soft during the first heating. This alloy is used for heating conductors in hobs, sensors and in flue gas cleaning. Ferritic steels can be magnetised.
Heat-resistant austenitic steel, mat. no. 1.4828
This material is heat-resistant to 1000°C as a result of its high chromium, nickel and silicon content. We stock this material in an annealed state.
Hard-rolled copper strip, mat. no. 2.0070 (SE-Cu58)
With a copper content of at least 99.95% and low oxygen and phosphorous content, the SE-Cu58 alloy is better quality than the generally used copper types, E-Cu (UNS C11000) and SF-Cu (UNS C12200). This material is used in general electrical engineering for cable straps and connectors, transformer coils, semiconductors and sheet metal parts (e.g. for seals).
Hard-rolled brass strip, mat. no. 2.0321
Composed of 63% copper and 37% zinc, this material is the standard product for spring-tempered, rolled brass. This material is not magnetic. Observe the roll direction when using the brass as a flat spring or when chamfering or bending brass.
Hard-rolled bronze strip, mat. no. 2.1020 (CuSn6)
With zinc content of 6%, the bronze alloy CuSn6 is the most frequently used type of bronze. Examples of typical applications are connectors, contact pins and general sheet metal parts and springs that require good electrical conductivity. Unlike brass, bronze can also be used in vacuum technology.
Pure nickel, mat. no. 2.4068 (Ni 99.2)
Pure nickel is very corrosion-resistant in alkaline media in particular, even at temperatures above 300°C. It is used in the chemical apparatus construction and pharmaceuticals industries. As nickel is resistant to chemical substances, the absolute purity of the product being processed is ensured. In thicknesses from 0.01 to 0.05 mm, nickel is available in a hard-rolled state; in thicknesses from 0.10 to 0.30 mm, it is available in a semi-hard state
Aluminium alloy EN-AW 8079
Due to its low specific weight and good formability, aluminium can be used for a wide range of applications. EN-AW contains iron and silicon, giving it a higher tensile strength. This allow is therefore used for aluminium foils of a thickness of up to around 0.05 mm.
Pure aluminium, mat. no. 3.0502 (Al 99.0%)
Due to its relatively good thermal conductivity, pure aluminium is also used for heat exchangers (however, alloys 3003 or 6063 should be used in soldered heat exchangers). As a result of its high electrical conductivity, aluminium can also be used in the electronics industry and, thanks to its high reflective properties, in lamp reflectors too.

NiCr8020
2.4869
NO6003
NiCr80/20
Contains long life additions making it eminently suitable for applications subject to frequent switching and wide temperature fluctuations. Can be used at operating temperatures up to 1150 °C.
Control resistors, high temperature furnaces, soldering irons.
NiCr6015
2.4867
NO6004
NiCr60/16
A Ni/Cr alloy with balance mainly Iron, with long life additions. It is suitable for use up to 1100 °C, but the higher coefficient of resistance makes it suitable for less exacting applications than 80/20.
Electric heaters, heavy duty resistors, electric furnaces.
NiCr3718
 
 
NiCr37/18
Balance mainly Iron. Suitable for continous operation up to 1050°C, in furnaces with atmospheres which may otherwise cause dry corrosion for higher nickel content materials.
Electric heaters, electric furnaces (with atmospheres).
COPPER NICKEL
