Copper silicon 90/10, 85/15, 80/20

CuSi 90/10, 85/15, 80/20

Description

Silicon copper is a copper master alloy typically used to make copper alloys, e.g. CuSiMn or CuNiSi and can thus consolidate some copper alloys from approx. 3% addition.

In addition to the basic metal, these alloys usually contain silicon or other alloying constituents in various weight fractions.

Quality

Copper:  residual copper plus typical impurities

Silicon:  9.0-11.0%, 14.0-16.0% or 19.0-21.0%

Unless otherwise agreed, the quality shall be in accordance with EN 1981: 2003,

At 10% Si content according to the material number CM231E (A) or with somewhat higher impurities CM232E (B),

At 20% Si content according to material number CM233E (A) or slightly less pure CM234E

The master alloy of 15% can be produced by adjusting the Si content with the impurity specifications of the above-mentioned materials

Packaging

CuSi 10 is supplied in approx. 10 kg of ingots with a typical dimension of 415x70x50 mm on pallets, 15% content of Si in fractions of this in barrels.

Storage

Like all metals and master alloys for melting, CuSui should be stored dry.

Availability

Copper silicon is usually produced by order.
