A World Class Manufacturer of Aluminum Brazing Sheets

Leading Brazing Aluminum Alloy Technical

Automobile weight reduction leads to improved fuel consumption and helps reduce CO2.

HDM selects the optimal combination of core materials and brazing materials from our diverse library of alloys. We do this to ensure that our products are suited to their intended environment and meet the needs of each particular customer.

At HDM, we develop highly reliable aluminum materials by determining the brazing material and cladding ratio of the alloy, creating a diffuse interface through the metallic composition of the core materials, and using flow control to form strong and dependable joints.

To ensure that heat exchangers have high corrosion resistance, we determine the compatibility of the brazing material with the material to which it will be attached (either fin or tube materials). We then decide on the alloy to be used as the core material, its metallic composition, and optimal tempering.
