AlSi 1 %, AlSi 1 % CR, ALW-29C

A homogeneous distribution of finely dispersed silicon precipitates achieves a high strength for wires with diameters < 100 µm. Moreover, the homogeneity of the silicon distribution permits the best processing conditions. The AlSi 1 % alloy is also available in the CR variant, which displays particularly corrosion resistant properties.
