Useful information about Brass
Brass and Bronze both are metal alloys and both are mainly used in our daily life. Brass is an alloy of copper and zinc, Bronze is an alloy consisting mainly of copper, combined most often with tin, but at times also with other metals. Brass has higher malleability than zinc or copper. Low melting point (900 c); flows when melted. While Bronze is hard and brittle. Melts at 950 centigrade but depends on amount of tin present. There is a bit difference in both colors. Brass color is muted yellow, somewhat similar to gold, but duller while Bronze is Reddish brown.
| Metal | Melting Point Celsius | Melting Point Fahrenheit |
| Brass (85 Cu 15 Zn) | 900-940 | 1652-1724 |
| Bronze (90 Cu 10 Sn) | 850-1000 | 1562-832 |
As written in Wikipedia, Brass is a metallic alloy that is made of copper and zinc. The proportions of zinc and copper can vary to create different types of brass alloys with varying mechanical and electrical properties. It is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure.
In contrast, bronze is an alloy of copper and tin. Both bronze and brass may include small proportions of a range of other elements including arsenic, lead, phosphorus, aluminium, manganese, and silicon. The distinction is largely historical. Modern practice in museums and archaeology increasingly avoids both terms for historical objects in favour of the all-embracing "copper alloy".
Brass is used for decoration for its bright gold-like appearance; for applications where low friction is required such as locks, gears, bearings, doorknobs, ammunition casings and valves; for plumbing and electrical applications; and extensively in brass musical instruments such as horns and bells where a combination of high workability (historically with hand tools) and durability is desired. It is also used in zippers. Brass is often used in situations in which it is important that sparks not be struck, such as in fittings and tools used near flammable or explosive materials.

Brass Characteristics
The exact properties of different brasses depend on the composition of the brass alloy, particularly the copper-zinc ratio. In general, however, all brasses are valued for their machinability or the ease with which the metal can be formed into desired shapes and forms while retaining high strength.| Grade | Shape | ||
