EUTECTIC XHD 1855

Description:
Very good resistance to cavitation, excellent resistance to marine corrosion, very high tensile strength, high elongation, low coefficient, very easily machinable. Aluminium bronze alloys are used to resist corrosion by sea water. XHD-1855 allows an entire range of these alloys to be welded with a Maximum Safety Margin. When the precise chemical composition of these base metals is unknown. XHD-1855 can be used as it provides an elongation up to twice that of traditional aluminium bronzes with comparable tensile strength. Greater elongation means: Less stress in the areas along the weld bead, less distortion of the part- less risk of cracking.

Very high tensile strength: The high tensile strength allows assemblies of the greatest safety to be made. XHD-1855 is
a Maximum Safety Margin electrode. Crack Resistance Because of its metallurgical structure, XHD-1855 has high elongation. This important property gives it very good resistance to cracking, both for joined assemblies and for very thick overlays.

Technical data:
Tensile strength Rm (MPa): 680
Yield strength Rp0,2 (MPa): 430
Elongation A,5 (%): 30
Hardness HB : 175

Applications:
Multi-Application; XHD-1855 is ideal for corrosion resistance of coating large surfaces used in the chemical industry. It may be used for assembling complex aluminium bronze alloys, for rebuilding and modifying aluminium bronze parts or for coating parts subject to intense metal to metal friction.
