Bronze

Our company distributes bronze raw material and products of the following shapes and applications for different purposes as follows:

Tin bronze - CuSn12

Standard: EN1982

Physical properties:

• Density: 8.6 g/cm3
• Melting range: 830-1000 °C
• Electrical conductivity at 20°C: 6.2 ms/m
• Thermal conductivity at 20°C: 54 W/(m*K)
• Linear coefficient of thermal expansion: 18.5 10-6/K

Mechanical properties:

• Tensile strength (rm): 260 MPa

• Melting range: 1042-1045 °C
• Electrical resistance μΩm 15°C: 15.6
• Thermal conductivity at 20°C: 50 W/(m*K)
• Linear coefficient of thermal expansion at 0-250°C: 16.2

Mechanical properties:

• Tensile strength (Rm): 470 N/mm2
• 0.2% yield stress (Rp0.2): 180 N/mm2
• Elongation (A): 20 %
• Brinell hardness (HB10): 110

Aluminium bronzes are characterized by high wear resistance and high corrosion resistance. Due to these properties, they are also used in heavily loaded machine parts and motors, sliding contacts, bearings, filters, bolts, coins and fittings.

Artist bronze - CuSn1Mn1Zn3Si3

Alloys of copper and 3% silicon and 1% manganese. Silicon bronzes have both good strength and ductility, as well as corrosion and abrasion resistance, 2.8... They can be welded well with 4.5% Si containing additive using the MIG process.

It is used in construction areas such as:

• for door fittings
• railings
• to the doors of churches
• for fittings, straps
• for fasteners for marine applications

It is also widely used in the chemical industry for heat exchangers and refrigeration technology, and is also an excellent material for coins and plaques. The alloy is a favorite material of sculptors and tinsmiths, thanks to its good machinability, durability and attractive gold bronze color.

Zamak ZnAl4Cu1

ZAMAK is a zinc-based alloy with alloys of aluminum, magnesium and copper. It is a low-melting, non-magnetizable grey alloy. Its typical application is the production of objects or ornaments with low mechanical stress, during which its excellent spreading ability, low melting point and easy casting are used. It is also perfect for pouring out complex shapes.

Our company sells ZAMAK 5 alloy to its partners, which contains 4% aluminum, 1% copper and 0.05% magnesium as alloys according to ISO: EN1774 standard tolerances and maximum impurities regulations.

Characteristic features:

• Density : 6,7 g/cm3
• Melting point : 380 – 386 °C
• Brinell hardness : 91 Brinell
• Presentation : in blocks
• Price : following the respective LME prices
