Produced from high purity copper chops using a high pressure water jet. Water atomized copper powder has an irregular shape and a high green strength property. This product is standardly used as an admix with iron powder parts to improve strength and mechanical properties.
Water atomized copper powder applications include:
- structural parts
- Conductive/Electrical components
- brazing pastes
Produced from high purity copper chops and atomized by a high pressure air stream. This production technique produces a powder that is semi-spherical in shape with higher green density compared to water atomized copper powder.
Air atomized copper powder applications include:
- polymer additive
- frangible bullets
- water filtration
- additive manufacturing
Electrolytic copper powders are produced by an electrolysis process and are characterized by increased purity and high green strength, due to the irregularity of the particle shape.
Applications for electrolytic copper powders include:
- carbon brushes
- electrical conductors
- diamond grinding wheels
Stainless Steel Powder
Produced from Type 316L stainless steel, this premium-quality stainless steel combines excellent corrosion resistance with outstanding abrasion resistance and toughness. Not only does it resist salt spray and acid spotting but it is also unaffected by strong alkaline cleaners and detergents. It will not chalk or tarnish. Along with good corrosion resistance, stainless steel flake has high specular reflectance, making it ideally suited for such applications as pigments for powder coatings and high-performance paints.
AMETEK Stainless Steel Flake is particularly useful because it will not form hydrogen when incorporated in water-borne coatings and consequently will not cause gassing. It eliminates problems with the popping of can lids. Leafing pigments are capable of concentrating at the surface of a paint film, where particles overlap each other, creating a metallic appearance.
Stainless Steel Flake products are available in 3 Grades:
Fine Leaf Grade Averages 25 microns
Standard Leaf Grade Averages 50 to 60 microns
Stainless Steel Paste Special grade with 10% mineral spirits
Powder Coatings: Use in automotive trim, wheels and under-the-hood parts, as well as office and outdoor furniture, and bicycles. Architectural Coatings: Provides a stainless steel look to masonry and exposed metal. Maintenance Coatings: Corrosion protection for food processing plants, transmission towers and equipment exposed to extreme elements. Cookware Coatings: Promotes abrasion resistance and heat transfer in non-stick coatings.
Lower Explosive Limits. Tests conducted by an independent laboratory show stainless steel to be stable in powder coatings. The US Bureau of Mines categorizes explosion hazards of materials as None, Weak, Moderate, Strong and Severe. Stainless Steel falls into the "none" Category.
