Brass
Properties: Very high resistance to corrosion. Brass is a relatively malleable alloy that can be worked both hot and cold. Its resistance to corrosion as well as its ductility give it a pleasing surface appearance.

Zinc is used in brass to reduce the melting point of the metal and its electrical conductivity. It also increases its service life and mechanical durability.

Brass is the most widely used copper alloy. It is one of the main alloys used by the screw-machining industry (production of small turned parts in very large series). Brass is used to make tubes and pipes, foundry components, mechanical parts such as gears, bolts and nuts, faucets, locksmith's parts, hardware, decorative items, precision instruments, timepieces, decorative elements for furniture, musical instruments, quality photo lenses, decorative utensils in copperware, etc... It is also used in certain parts subject to wear and tear or shock (hood, underside) of cameras. Brass can also be used as a protective or decorative layer.

HIGH RESISTANCE BRASS
High Resistance Brass contains manganese and, depending on the grade, additions of nickel or silicon to improve its properties. These alloys have high mechanical properties. They resist well to climatic variations and show high performance during machining.

They combine high mechanical properties and good resistance to friction wear. In addition, they have good compressive and matting strength.

BRONZES
Mainly copper and tin alloy bronzes. Their main characteristics are strength, resistance to wear, medium resistance to corrosion and good electrical conductivity.

Bronzes also stand out for their resistance to shock. They are often used as a friction material facing steel involving high friction.
