7084 is a copper based filler metal containing about 1% iron used for gas-metal arc welding of copper, copper-nickel, brass, bronze, steel, galvanized steels and also cast iron. Most common applications would include marine maintenance and repair, ship propellers, pump housing, rigging jacks, piston heads, bearings and excellent for build-up or overlaying wear/corrosion resistance applications. Combinations of Copper or Aluminum Bronze base metals to steel are very common with this filler metal. Exhibits high mechanical properties and hardness.
