C17200 and C17500 and Alloy 190, C17200, CW101C Alloy M25, C17300, CW102C: It is identical to a version of lead-containing alloy 25 and achieves the same exceptional strength after hardening. This alloy is supplied as wires and rods which are mainly employed for machined products. Its low lead content improves its machinability (shorter chips and reduced wear of tools). The alloy is normally hardened after machining. Alloy M25, C17300, CW102C can however be soft-annealed again so that it can be crimped and electroplated. This alloy distinguishes by high endurance limit, outstanding relaxation resistance at exposure to heat and a unique strength-conductivity ratio. SAE J461, ASTM B441, ASTM B534 Alloy 174, C17410: Copper alloy with low beryllium content. It contains only few alloy elements: Beryllium and cobalt. Alloy 174, C17410 combines outstanding electric conductivity with high mechanical strength (typical values: 50% et 750N/mm2 Alloy 174 is supplied hardened so that a later heat treatment of the products is not necessary. This reduces production costs and prevents the deformation of the finished products. Although alloy 174 is supplied in hardened condition, it shows excellent bending behavior. This alloy distinguishes by excellent bending behavior in connection with mechanical strength and conductivity, which outperforms any other copper alloy of this price level. Alloy 360, N03360: Alloy 360, N03360 is a Nickel alloy containing approximatively 2 % of beryllium. It is used for all applications that require good elastical properties at elevated temperatures. Mechanical strength is rather high and when hardened is even higher than that of alloy 25. Beryllium copper and its variety of alloys are utilized in very specific and often tailor-made applications such as oilfield tools, aerospace landing gears, robotic welding, and mold making applications. Additional non-magnetic properties make it ideal for down-hole wire line tools. These specific applications are the reason this copper is known as spring copper and other various names.
