Precision CNC Machining China Tin Alloy Weldment Custom Fabrication Services

Tin alloy weldments are structural components manufactured using high-purity tin-based alloy materials through precision welding processes. Our products primarily employ eco-friendly alloy formulations such as Sn99.3/Cu0.7, exhibiting excellent welding performance and mechanical strength. During welding, tin alloys demonstrate superior fluidity and wettability, forming bright and饱满 solder joints. The outstanding oxidation resistance significantly reduces dross formation. These weldments are suitable for various processes including wave soldering and manual dip soldering, with operating temperatures typically controlled within 265±5℃ range to ensure consistent welding quality.

• High-Purity Materials: Utilizes high-purity metal raw materials processed through vacuum deoxidation, with strictly controlled impurity content (Pb≤0.05%), ensuring uniform composition and stable performance.
• Excellent Welding Properties: Features rapid wetting time and tensile strength up to 42MPa, with superior spread ratio compared to conventional solder materials, producing bright and full solder joints.
• Oxidation Resistance and Energy Efficiency: Special anti-oxidation formulation maintains mirror-like surface below 300℃, with dross generation only 1/7 of ordinary solder, effectively reducing energy consumption and maintenance costs.
• Environmental Compliance: Products comply with EU ROHS and WEEE directives, featuring halogen-free design that meets global environmental standards for export electronics.
• Precision Machining: Employs CNC precision machining technology to ensure dimensional accuracy and tight structure, enabling customized production of complex shapes.
