Brazing Alloy

There are special technical requirements for the welding of polycrystalline diamond composite (PDC) and polycrystalline cubic diamond boron nitride. After years of research, we have designed a series of special solder suitable for PDC and PCBN welding. In the manufacturing process of solder, all high-quality raw materials are used for production, and the leftover materials are completely removed in the processing process to ensure the stability of quality and reliable performance of products.

Application:

We have developed MAG 611-618 series of silver filler metals according to the working conditions of different industries, which are respectively suitable for brazing the workpiece under the conditions of normal temperature, medium temperature and high temperature or under the conditions of constant, alternating, vibration and impact load.

Sandwich composite filler metal is specially used for brazing large area workpieces, which has significant buffering effect on impact and vibration load.

Applicable technology

Induction welding (automatic induction welding), flame welding, furnace welding, resistance welding and other brazing processes, welding needs to be used together with the brazing flux.

Specifications:

Filament series: coiled wire with a diameter of 0.25mm or more, straight bar with a diameter of 1.5mm or more.

 

Band series: band or flat wire with a thickness of 0.10mm or more and a width of 2.2mm to 60mm

Sheet series: square sheet, rectangular sheet, round sheet, etc. and other preformed sheets with special requirements;
