The simple answer to repairing and welding aluminium - Durafix Easyweld Rods
Durafix Easyweld is a unique 3 in 1 application. Brazing, Soldering or Welding Aluminium is now as easy as 1-2-3. There is no need for expensive equipment. No need for years of welding experience. It's convenient and can be used by both novice and professional alike.
Durafix Easyweld is the most widely used rod on the market for welding zinc based metals - white - die cast - pot metals. Welds made with the rod are clean and free from slag, and produces a sound joint which is stronger than the parent metal.
Welding aluminium without the use of flux, produces a joint sound and free from porosity. Durafix Easyweld will work on galvanised steel, also used as a Rub-on solder. Use a slightly carbonized flame ( excess of acetylene ), with small tip for most work.
Durafix Easyweld carries the following classifications:
- ASTM no. B240
- US Army - Engineering Corp - Spec no. MIL-R-4208

Durafix Easyweld product applications and simple guides.
Durafix Easyweld will work with propane, butane, mapp, oxyacetylene or any
fuel source as long as the material is brought up to 389'C ( 732'F ) before applying the rod.
The material must be cleaned with a stainless steel brush only.
