Classification

Brass (an alloy based on 55% — 96% Cu + 45% — 4% Zn) is classified:

1. On the delivery status — foundry or deformable;
2. Hardness: soft, semi-hard and hard;
3. By structure: single-phase and two-phase alloys;
4. By the degree of preliminary deformation;
5. By the form of the previous heat treatment.

Technical specifications

When brass has the structure of an α-solid solution, an increase in the content of zinc causes an increase in its strength and plasticity. The appearance of the β'-phase is accompanied by a sharp decrease in ductility, strength continues to increase with an increase in zinc to 45%, while the brass is in a two-phase state. The transition of brass into a single-phase state with a β'-phase structure causes a sharp decrease in strength. Brass containing up to 45% Zn is of practical importance. Alloys with a high content of zinc are highly fragile. Single-phase, α-brass includes L96 (tombak), L80 (semitopack), L68, which has the greatest plasticity (d5 = 56%). Two-phase grades L 59 and L60 have less ductility in the cold state, but greater strength and wear resistance. Single-phase ones after annealing have Sv = 250… 350 MPa and d5 = (50… 56)%, two-phase — Sv = 400… 450 MPa and 5 = (35.40)%.
