Brass Welding
BRAS TECH are Copper and Zinc-based Filler Metals (Brass), used for joining ferrous metals and non-ferrous metals. They can be used in various types of Brazing Processes, commonly including flame and induction. They are very economical filler metals, mainly used in joining steels. Overheating must be avoided by avoiding the presence of final porosity due to the evaporation of Zinc.
INFORMATION: BRAS TECH 35 is used in joining with steels, copper, copper alloys, nickel, nickel alloys and stainless steel where corrosion is not important. It is necessary to use an adequate flow. Clearances of the order of 0.08 to 0.13 mm are recommended.
INFORMATION: BRAS TECH 35 Ni is similar to BRAS TECH 35, however, it has greater additions of Tin and Silicon. It also contains Mn from 0.2 to 1.0 which makes the alloy less subject to residual porosity due to the loss of Zinc through evaporation. It also contains additions of Manganese and Iron that provide greater mechanical resistance.
INFORMATION: BRAS TECH 38 is similar to BRAS TECH 35, being used in the same applications, however the addition of Silver improves the fluidity characteristics of these alloys, which are generally not good.
INFORMATION: BRAS TECH 05 is a filler metal already considered as a Silver alloy due to its content of 5% in the alloy. This presence of Silver gives the filler metal a good fluidity characteristic. Due to the low quantity of Silver, it becomes an interesting option in terms of cost-benefit.
INFORMATION: BRAS TECH 912 is an addition alloy based on Copper, Zinc and Nickel commonly called Alpaca. Widely used in welding Tungsten Carbide (Carbide). It is also used in joining Steel, Nickel and Nickel alloys. Features high mechanical resistance joints.
INFORMATION: BRAS TECH 506 is an addition metal similar to BRAS TECH 912, having a lower Nickel content which leads to slightly lower brazing temperatures and a slightly lower resulting mechanical resistance.
