W7 Bronze is a high leaded, tin based alloy engineered for components that demand excellent machinability and moderate load bearing capability. The combination of copper, tin, lead, and zinc gives this alloy good wear resistance, corrosion protection in brine and seawater, and dependable performance in pumps, valves, bearings, and bushings. We are a reliable supplier of Bronze, offering high quality materials for diverse industrial applications.
The alloy’s leaded structure supports smooth machining while maintaining strength and durability. W7 Bronze also offers excellent sliding and dry running performance, making it well suited for bushings, seating rings, and other precision components exposed to moderate operating stresses. As a trusted non ferrous metal trader in the UAE, we supply W7 Bronze to customers across Saudi Arabia and Oman for a wide range of industrial applications.
Key Advantages & Uses of W7 Bronze
- High tensile strength (~205–240 MPa) and proof strength (~100–140 MPa) for medium load applications
- Excellent machinability due to lead content for precise component fabrication
- Good wear and abrasion resistance under sliding contact and moderate loads
- Corrosion resistance in brine and seawater; not prone to dezincification
- Thermal stability with melting range ~977 °C and moderate thermal expansion (~18 ×10⁻⁶ /K)
