Alpha-beta brasses:

Alpha-beta brasses contain 55–65% copper and 35–45% zinc. these brasses, also known as duplex brasses,are suitable for hot working.

Beta brasses:

Beta brasses contain 50–55% copper and 45–50% zinc. these brasses can only be worked hot. they are harder,stronger,and appropriate for casting.

Gamma brasses:

Gamma brasses contain 33-39% copper and 61-67% zinc. there are also ag-zn and au-zn gamma brasses,with ag 30-50% and au 41%,respectively. the gamma phase is an intermetallic compound with a cubic lattice structure, cu5zn8. gamma brasses are typically used for specialized applications,including high-strength electrical contacts and fasteners.

Composition and Properties of Brass

The primary components of brass are copper and zinc.the ratio of these two metals can vary,resulting in different types of brass with unique properties. the composition of brass is generally 66% copper and 34% zinc. however,by weight,brass contains between 55% to 95% copper and 5% to 45% zinc. elements such as lead,tin,or aluminum can also be added to brass to enhance specific characteristics.lead promotes corrosion resistance and machinability,whereas iron increases hardness and facilitates alloy forging easier.

Process of Brass Profiles

Step 1. Mining and processing copper ore into copper metal which is almost 100%, pure copper. Zinc ore is also processed into nearly pure zinc metal.

Step 2. The purified copper and zinc metals are heated to melting points of 1083°C and 419 in a furnace according to the desired brass composition.

Step 3. The molten metals are mixed thoroughly to form brass according to predetermined percentages of copper and zinc.Impurities and bubbles are removed.

Step 4. The molten brass is poured into molds to cast it into bars, ingots, or other shapes; or extruded through dies to form tubes, rods,or plates.

Step 5. The cast or extruded brass is often treated using techniques like annealing, cold working,grinding, or polishing to improve properties,strength,hardness,surface finish,machinability,or corrosion resistance.

Step 6. Additives like lead,tin,aluminum,or manganese are sometimes included in the composition to produce brass alloys with specific properties depending on the intended application.

Step 7. Once cooled and treated,the brass product is finished and ready to be fabricated or used for its intended purpose.Final inspections verify that it meets the required standards.
