Supplier — AvekGlob Company — offers at a reasonable price from the manufacturer a wire, circle or rod made of bronze C93200 (2.1090, CuSn7ZnPb). The supplier guarantees the timely delivery of products to any address specified by the consumer.

Technical specifications

Bronze brand C93200 (also called alloy CuSn7ZnPb, alloy 2.1090) belongs to the group of doped tin bronzes, which contain an increased percentage of lead and zinc. Good plastic characteristics of the material make it possible to produce from it a variety of profiles: cast semi-finished products of various sizes and shapes, as well as finished products — anodes, rods, blanks for subsequent rolling, forging or cold stamping. In the latter case, bronze C93200 (CuSn7ZnPb, 2.1090) produces square, hexagonal and circular profiles, as well as slabs and strips.

Urgency of application

The greatest use of bronze grade C93200 (CuSn7ZnPb, 2.1090) finds in the automotive industry, where it is used in the manufacture of various automotive fittings and fasteners. Typical parts that are made of this material are various ring and tubular structural elements, nuts operating under load, and discs operating at significant mechanical pressures and a lack of process lubrication.

Chemical composition

In accordance with the ASTM B505 standard, this bronze contains the following elements (numerical data — in percentages):

Notes. 1. In the production of alloy in castings, the permissible content of lead is up to 1.5%. 2. Copper of chemical purity is used not less than 99%, while in copper, a partial content of nickel is allowed. 3. Nickel may contain traces of cobalt.
