Investigating an Alloy - Brass

Extracts from this document...


´╗┐Arun Bir 04/01/2012 Investigating an Alloy - Brass Introduction: Brass is an alloy of copper and zinc; the proportions of zinc and copper can be varied to create a range of brasses with varying properties. In comparison, bronze is principally an alloy of copper and tin. Bronze does not necessarily contain tin, and a variety of alloys of copper, including alloys with arsenic, phosphorus, aluminium, manganese, and silicon, are commonly termed "bronze". ...read more.


It is also used in zippers. Because it is softer than most other metals in general use, brass is often used in situations where it is important that sparks not be struck, as in fittings and tools around explosive gases. Brass has a muted yellow color which is somewhat similar to gold. It is relatively resistant to tarnishing, and is often used as decoration and for coins. ...read more.


By varying the proportions of copper and zinc, the properties of the brass can be changed, allowing hard and soft brasses. Today almost 90% of all brass alloys are recycled. Because brass is not ferromagnetic, it can be separated from ferrous scrap by passing the scrap near a powerful magnet. Brass scrap is collected and transported to the foundry. Aluminum makes brass stronger and more corrosion resistant. Aluminum also causes a hard layer to be formed on the surface that is thin, transparent and self healing. ...read more.
