Manufacture
Percentage composition according to EN12165
| Cu | Zn | Pb | Sn | Ni | Fe | Sb | S | P | Si | Si | Residual elements |
| Basis | 7−10 | 6−8 | ≤ 1 | ≤ 0.4 | ≤0.25 | ≤0.08 | ≤0.02 | ≤0.005 | ≤0.005 | ≤0.005 | ≤0.08 |
Miscibility of metal in liquid alloy is performed in two steps. The first step is kinetic. Valence bindings split in crystal lattice of liquid material. There are formed new bindings between atoms of liquid metal and other atoms that are contained in solution. This step is done in boundary layer of liquid metal. During second step, solute atoms diffuse into solution through boundary layer of liquid metal.
Application
Application of semi-red brasses: decorative brass, valves, cages, parts of water pipelines, furniture fittings, decorative casting, fittings, radiator parts, battery terminals, bushings, castings of general purpose with average strength.
Installation
Parts made of semi-red brasses can be joined by brazing (with a help of braze solders). There is not recommended to use such types of welding: arc welding in atmosphere of protective gas, carbon electrode welding, oxy-acetylene welding.
