Brazing material copper solder paste

Description of the copper brazing paste.

Cemented carbide tools used solder variety, dosage is one of the largest copper metallurgical and silver based solder. Pure copper brazing alloy and copper base filler metals is the most commonly used solder when brazing carbide. Pure copper solder joint high plasticity, but in working temperature higher than 320 ℃, the joint strength rapidly reduced, therefore, not suitable for working under high temperature. Melting temperature is lower than the purity of copper base filler metals are mostly base copper zinc alloy, adding manganese nickel elements such as improve the weld strength, at 320 ℃, has higher strength.

Silver based solder, comprehensive performance is better than that of copper base filler metals are also often join manganese nickel improve the wettability of solder, improve the weld strength and joint working temperature. Silver based solder brazing temperature is usually lower than copper base filler metals.

In operating temperature above 500, carbide brazing joint strength to demand higher, can use cobalt nickel metallurgical and metallurgical.
