Semi-red brass alloy and purchasing details
Specify the UNS, ASTM, EN or project designation rather than relying only on the general term semi-red brass. Include whether rod, bar, tube, pipe, sheet, strip, a casting or a machined blank is required, together with dimensions, condition, tolerances, testing, certificates, quantity and destination ZIP code. C84200, C84400, C84500 and C84800 are distinct alloys and are not treated as interchangeable.
Technical characteristics
Semi-red brass is brass alloy that contains 8−17% of zinc, and nit less than 78% of copper. This is a modern substitute of tomboy. Alloys that relate to semi-red brass: C84200, C84400, C84500, C84800. Due to modern technological possibilities, there are can be manufactured the most complex details out of semi-red brass.
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.
