At HIH Technologies, we prioritize quality to extend the life and enhance the performance of your tools. Our CANADIAN TOUGH brand of Composite Brazing Rods is made from only the highest-quality upcycled sintered carbide materials. No ‘rocks’ in the braze pool—just superior, finely crushed carbide. Every year, we upcycle over 200,000 lbs. of sintered WC to create our CANADIAN TOUGH products.
