Copper

Product Features

Copper Cu-ETP (E-Cu57) and low-alloy copper grades.

Cu-ETP (Electrolytic Tough Pitch Copper) is a widely used copper grade with a purity of ≥99.9%. It has excellent electrical and thermal conductivity, but is susceptible to hydrogen embrittlement at high temperatures. Applications include electrical cables and power rails.

Low-alloy copper combines copper with small amounts of other elements for additional strength, wear resistance or machinability:
CuBe2 and CuCo2Be (beryllium and cobalt-beryllium copper) offer high strength and good electrical properties, ideal for spring contacts and spot welding electrodes. CuCr1Zr and CuNi2Si (chromium-zirconium and nickel-silicon copper) are wear-resistant and heat-resistant, suitable for welding technology and electrical components. CuTeP (tellurium copper) has excellent machinability with minimal impact on electrical conductivity, ideal for precision machining.
These alloys are widely used in electrical, mechanical and welding engineering.

Brass

Product Features

Standard, eco- and high-tensile brass.

Brass is a copper-zinc alloy that acquires specific properties through the addition of other elements. The most common brass alloy (CuZn39Pb3) contains lead for excellent machinability and is widely used in fittings and valves. Eco-brass (CuZn21Si3P) replaces lead with silicon, making it more environmentally friendly without much loss of machinability, ideal for potable water installations.

For higher strength and wear resistance, high-tensile brasses have been developed. CuZn35Ni3Mn2AlPb (CuZn35Ni2) and CuZn37Mn3Al2PbSi (CuZn40Al2) combine strength with good machinability and are used in heavily loaded mechanical parts. CuZn25Al5Mn4Fe3 (CuZn25Al5) offers maximum wear and corrosion resistance, ideal for marine and industrial applications.

Although the base remains copper and zinc, the alloy determines the final strength, machinability and resistance to wear and corrosion.

Phosphor-tin bronze

Product Features

CuSn6 (sheet) and CuSn8 (round bar, flat/square, hexagon) are copper alloys with 6% and 8% tin, respectively, reinforced with phosphorus for high wear and corrosion resistance. CuSn6 has good ductility and is widely used in springs and electrical contacts, while CuSn8’s higher hardness makes it ideal for machine parts and bearings.

In the food processing industry, these alloys are used in machine components such as bearings and guides, but less so for direct food contact because of their copper content. Their durability and resistance to moisture make them suitable for indirect applications.

Lead Bronze

Product Features

Lead bronze is an alloy of copper, tin and lead, known for its excellent wear resistance and machinability. CuSn10Pb10-C, or lead bronze 10 (10% tin, 10% lead) is often used in bearings and other parts subjected to heavy loads and friction. The lead lowers friction and improves castability, making it ideal for applications requiring wear resistance.

CuPb15Sn, or lead bronze 15 has an even higher lead content (15%) and is used for heavier duty applications, such as bearings and clutches. Due to the higher amount of lead, this alloy has excellent emergency running properties and offers excellent performance in heavy-duty, low-speed environments.

Both alloys are popular in the engineering and automotive industries, but are being used less and less because of environmental and health concerns surrounding lead.
