Brownells Hi-Force 44 Solder is a non-toxic alloy with 4% silver, ideal for joining steel, stainless steel, nickel, brass, and copper.
It melts and flows at approximately 475° F, providing a strong bond with 14,000 to 28,000 PSI tensile strength without the need for oxyacetylene setups.
The solder is resistant to black oxide formation and can withstand immersion in hot bluing tanks without damage to the joint.
