Brief Alloy Range Descriptions:
Aluminium alloys are the most widely used of the non-ferrous metals, offering low density, good strength levels, excellent general corrosion resistance, high conductivities and good elasticity. Another attractive property of aluminium alloys are their ability to be recycled making it very cost effective for many components. Their high strength to weight ratio mean they are critical for weight sensitive industries such as aerospace and automotive.

Phosphor Bronzes, Leaded Gunmetals and the Leaded Bronzes are generally alloys of copper and tin with other additions (notably lead, nickel and phosphorus to improve their wear resistance, corrosion resistance, machinability / lubricity and the strength levels of the alloys.
Stock range includes: PB102 / C51000 / CuSn5 / CW451K, PB104 / C52100 / CuSn8 / CW453K, LG1 / CC490, LG2 / CC491, PB1 / CC481K, SAE660 / CW497K
Coppers of 99.5% purity or greater are primarily used for their high electrical and thermal conductivity values but also offer good corrosion resistance. The conductivity values generally increase as the purity level increases with the C110 oxygen free electronic grade being the ultimate grade available. However, silver bearing coppers offer a resistance to softening combined with maximum conductivity values, while sulphur and tellurium can be added to improve machinability.
Stock range includes: C101 / Cu-ETP / CW004A, C106 / Cu DHP / CW0024A, C103 / Cu-OF / CW008A / BS1433, C110 / Cu-OFE / CW009A / BS3839, C109 / CW118C / CuTe / C14500, C111 / C14700 / CW114C / CuSP, CW011A, Cu-Ag-2, CW012A, CW013A, IEC 60356, JIS C 2801.
Copper Nickel or cupronickels offer excellent corrosion and erosion resistance in offshore and marine environments and dependent on the nickel content the grade can offer a good formability and high ductility, or a high strength and modulus for more demanding applications. The copper nickel alloys also offer a very high resistance to hydrogen embrittlement and a retention of mechanical properties at cryogenic temperatures.
Stock range includes: CN102 / C70600 / CuNi10Fe1Mn / CW352H, CN107 / C71500 / NES 780 / CW354H, DIN 2.1504 / DTD900/4805, NES 835 / DSTAN 02-835.
Other copper alloys available:
Copper Chromium Zirconium was developed to give a combination of high strength, very good thermal and electrical conductivities with a retention of mechanical properties up to 525¿C. Specifications include CC102 / BS4577 A/2/2 CW106C
Copper nickel silicon alloys such as CuNi2Si / C64700 or CuNi3Si CW112C offer a fantastic combination of physical and mechanical properties for high performance engineering. The excellent balance of very high strength, excellent wear resistance and very good electrical and thermal conductivities. These attributes combined with an ease of machinability make a cost effective and superior alternative to many other copper based materials.
