Import Brazing (Cu-Ag) Series — Buy in Bulk from Supplier in China

The Brazing (Cu-Ag) Series from Hongkong SSTS Welding Metal Co., Limited includes low and high silver content copper-based brazing rods, such as Bcup-2 and Bag-20. These rods are manufactured in Ningbo, China, with over a decade of production experience, and are available in round, flat or ring forms to suit diverse brazing applications. The series covers a range of silver (Ag) and copper (Cu) compositions, with melting points spanning 618°C to 925°C to accommodate different material and joint requirements.

Low silver variants like Bcup-2 (6.8 - 7.5% Ag) are economical and widely used in air-conditioning and gas appliances due to their good flow properties and liquidus temperatures around 795°C. High silver variants such as Bag-20 (29 - 31% Ag) offer lower melting points (677 - 766°C solidus-liquidus) and superior wetting, making them ideal for brazing copper, copper alloys and steel in precision applications like aerospace or electrical components. Standard industry classifications for these alloys follow AWS and JIS codes.

These brazing rods are used in industries including HVAC, automotive, electronics and food processing, where strong, leak-proof joints are critical. The supplier offers sizes from 0.5 mm to 5 mm in diameter, with packaging options like spools (15 kg), coils (10 kg) or boxes (500 kg). Buyers should confirm size availability, packaging and incoterms, as these are not fully specified for all variants.
