Bronze is a copper-based alloy, mainly composed of copper and tin, sometimes with other elements such as aluminum, manganese, nickel or zinc added. Bronze has excellent mechanical properties, corrosion resistance and wear resistance, and is widely used in machinery manufacturing, construction, art and electrical fields.
There are many types of bronze metal products, which can be classified according to different standards. The following are some common bronze products and how they are classified:
Classification by form
Plate (bronze plate)
Thick plate: thickness greater than 5mm.
Thin plate: thickness between 0.1mm and 5mm.
Foil: thickness less than 0.1mm.
Rod (bronze rod)
Round rod: round cross section.
Square rod: square cross section.
Hexagonal rod: hexagonal cross section.
Tube (bronze tube)
Seamless bronze tube: no welding, integrally formed.
Welded bronze tube: formed by welding process.
Wire (bronze wire)
Bare bronze wire: bronze wire without insulation layer.
Insulated bronze wire: bronze wire covered with insulation layer.
Strip (bronze strip)
Narrow strip: width less than 300mm.
Wide strip: width greater than 300mm.
Classification by use
1. Bronze for machinery and structure
Gears, bearings and bolts: used for mechanical parts.
Pipe fittings and valves: used for piping systems.
2. Bronze for decoration and construction
Architectural decoration materials: such as bronze plates and bronze tubes.
Furniture accessories: such as bronze handles and hinges.
3. Bronze for electrical and electronic applications
Electrical connectors and terminals: used for electrical connections.
Electrical housings: such as housings and panels of electrical equipment.
4. Bronze for musical instruments and crafts
Musical instruments: such as accessories for brass and stringed instruments.
Crafts: such as sculptures, trophies and decorations.
5. Bronze for marine and chemical applications
Ship accessories: such as propellers and ship pumps.
Chemical equipment: such as reactors and heat exchangers.
Divided by processing technology
1. Hot-rolled products: formed by rolling at high temperatures.
2. Cold-rolled products: formed by rolling at room temperature, with higher dimensional accuracy and surface quality.
3. Extruded products: formed by extrusion process, usually used for bars and pipes.
4. Forged products: formed by forging process, with higher mechanical properties.
5. Casting products: formed by casting process, suitable for parts with complex shapes.
