  1. How hot does it have to be?
    730 Degrees
  2. What is the sheer strength?
Physical Properties
  • Rockwell B. Hardness: 55 to 60 depending upon cooling rate(kg load, 1/16 ball)
  • Ultimate tensile strength Greater than base aluminum, up to 40,000 pounds per square inch
  • Shear Strength: 18,000 to 33,000 pounds per square inch depending upon joint design.
  • Corrosion Penetration: Less than 300 x 10 -6 inches per year
  • Working Temperature: 730 degrees farenheight

No Flux Required to make any repair
Now anyone can repair aluminium and other non-ferrous metals

Fire and Explosion
Hazard Data
  • Flash point (test method): n/a
  • Flammable limits: n/a
  • Extinguishing media: co2 or dry chemical extinguisher - do not use water
  • Special fire fighting procedures: co2 or dry chemical extinguisher - do not use water [use niosh/msha self-contained breathing apparatus]
  • Unusual fire and explosion hazards: heating metal beyond boiling point results in evolution of zinc vapor which immediately reacts with air to form zinc oxide fumes.
Special Protection Information

We recoment that you wear EYE PROTECTION AND GLOVES at all times when working.

If heated to over 2400 degrees F (boiling point of Zinc)
OTHER PROTECTION: Follow Federal, State, Local, OSHA statutes for specific application.
