Characteristics of hot-forged Brass

- Hot-forged brass offers better mechanical characteristics than die casting

- Hot forging allows important deformations, refines the starting grain, produce a strain hardening, create a favorable linear drawing by considerably improving the mechanical characteristics

- Hot-forged brass offers the advantage of excellent material health, good surface condition, no porosity, very good waterproofing allowing an easy polishing and numerous coating like nickel plating, chrome plating, tinning, varnishing and painting.

- Brass also offers a really good corosion resistance

- Recycling brass is easy and economical, environmentally friendly

The different brass families

Standard brass with about 60% copper, Good ductility for hot forging

Used in mechanic, hydraulic, heating, distribution of water and gas
