BB05xi is a low-alloyed copper alloy which exhibits an electrical conductivity similar to CuFe2P. Small additions of xi improve softening. The alloy does not reach the spring force of the bronzes, however, in comparison with pure copper, the alloy is significantly harder and in comparison to CuFe2P, which is very often used in a hot dip 0nned condition for lead frames for applications in an0-skid, ESP and transmission control systems, BB05xi can easily be recycled. BB05xi has excellent soldering and welding properties, especially Laser welding. The alloy is an ideal solid solution alloy. There is no Zn evaporation during welding or other influence of precipitates on the laser beam. BB05xi meets with respect to Pb and Cd the OEKO-TEX Standard 100.

SB20 is an age-hardening CuNiSi alloy for current-carrying formed parts on which particular requirements are placed. It has an α-structure with very fine precipitations and recommends itself both for lead frames which require a high rigidity of the pins and for connectors with particularly high demands on the electrical conductivity with average strength and good relaxation behaviour. SB20 in hot-dip tinned condition shows a very good adhesion of the tin layer at higher application temperatures. In addition, SB20 is also suitable for current -carrying formed parts and contact springs due to its good fatigue strength, forming and spring properties. The alloy is registered with the U.S. EPA as Antimicrobial.

SB21 is an age-hardening CuNi1,5Si alloy for current-carrying formed parts on which particular requirements are placed. It has an α-structure with very fine precipitations and recommends itself both for lead frames which require a high rigidity of the pins and for connectors with particularly high demands on the electrical conductivity with average strength and good relaxation behaviour. In addition, SB21 is also suitable for current -carrying formed parts and contact springs due to its good fatigue strength, forming and spring properties. The alloy is registered with the U.S. EPA as An-microbial.

SB22 is an age-hardening CuNi2Si alloy, higher alloyed in comparison with SB21, for current-carrying formed parts. It has an α-structure with very fine precipitations and recommends itself both for lead frames which require a high rigidity of the pins and for connectors with high demands on the electrical conductivity, strength, thermal load and relaxation behaviour. In addition, SB22 can also be used for current-carrying formed parts and contact springs due to its good fatigue strength, forming and spring properties. The alloy is registered with the U.S. EPA as Antimicrobial.

SB28 is an age-hardening CuNi3Si alloy, that, in comparison with SB22, has higher contents of nickel and silicon with additions of magnesium in order to be able to adjust a particularly high strength and stress relaxation resistance. It has an α-structure with very fine precipitations and recommends itself both for lead frames which require a high rigidity of the pins and for connectors with particularly high demands on strength, electrical conductivity, thermal load and relaxation behaviour. In addition, SB28 can also be used for current-carrying formed parts and contact springs due to its good fatigue strength, forming and spring properties. The alloy can be surface-refined to various procedures The alloy is registered with the U.S. EPA as antimicrobial.

SB92 is a cupro-nickel 10 material to which approx. 2 % 0n is added. It is mainly used for spring-ac0on parts. SB92 is distinguished by a very good stress relaxation behaviour in spring hard condition, a good tarnish resistance as well as a high softening temperature. By means of an additional tempering after the cold forming process the bendability can be considerably improved. The alloy is registered with the U.S. EPA as Antimicrobial and with respect to Pb and Cd meets the OEKO-TEX Standard 100.

SB35 is a further developed multi-alloy bronze which is distinguished by its high electrical conductivity, outstanding strength and a good bending behaviour. Due to the manufacturing process chosen and the balanced chemical composition SB35 exhibits an excellent resistance to stress relaxation. Similar to bronze, SB35 is used as a material for current-carrying spring elements. The alloy is registered with the U.S. EPA as Antimicrobial and with respect to Pb and Cd meets the OEKO-TEX Standard 100.
