Eutectic 21071 is a gas atomized aluminum bronze alloy powder designed to produce homogenous coatings with both Plasma spray and Combustion spray processes. 21071 meets the requirements of MIL-STD 1687. Excellent self-bonding properties mean that a separate bond coat material is not required. Each lot of powder is subjected to extensive quality checks to insure a consistent particle size distribution, chemical composition and reliable coating performance. Coatings have exceptional cohesive strength that permits thick coatings to be applied

• High quality machinable coatings for soft bearing applications
• Repeatable, high integrity coatings with minimum operator technique required
• May be used on steel and copper alloy parts to restore dimensions
• Excellent corrosion resistance in caustic solutions
• Versatile welding capability on a variety of base materials
• Efficiency: After the initial bond pass at 5 lb/hr the coating rate can be increased to 14 lb/hr without sacrificing coating quality or deposition efficiency
• Deposit efficiencies of 85 - 90% are normal when using the TeroDyn System 2000 combustion spray torch
• No deformation or structural change in base metal
• 15 sec hall flow rate
• Rockwell B scale 60 hardness
• 3000 psi on LCS bond strength (ASTM C633)
• Less than 5% porosity
• As sprayed 530 ?in AA, finished >15 ?in AA surface roughness
