Nickel powders, flakes and oxides
Australian Metal Powders Supplies represents Novamet Specialty Products in Australia.
Novamet produces more than 60 different products including tightly sized nickel powder, metallic flake, coated materials and specialty nickel oxides.
Novamet specialises in small volumes and custom products. Using its screening and classification capabilities, the plant makes precision-engineered products to the most exacting specifications. Novamet also repackages Vale Inco nickel powders to both Novamet standard and customer-specific containers and weight requirements.
Nickel powder type 123
Vale Inco Type 123 nickel powder is a spherical nickel powder produced to a controlled particle size and apparent density range. The combination of fine particle size, dendritic surface, high purity and unique shape have spurred a long list of applications including high purity magnetic alloys, silver-nickel electrical contacts, welding electrodes, anti-seize lubricants, friction components, nickel catalysts, roll compacted strip and organo-nickel compounds.
Conductive nickel powders
Type 525 nickel powder is a high purity filamentary powder that has been screened to remove large or agglomerated particles. It is used in conductive coatings, adhesives and gaskets. Type 525 powder's excellent corrosion resistance, good conductive properties and unique filamentary shape make it very effective in radio frequency and electromagnetic shielding coatings. Small amounts added to coil coatings enhance weld ability. Two versions of Type 525 nickel powder are available.
Conductive Nickel Spheres (CNS) were developed for use in conductive inks and pastes where their uniform size, smooth spherical shape and low surface area allow for maximum compaction of the nickel particles in the binder matrix. CNS can also be silver or gold plated. Up to 30% of CNS can be blended with pure silver without a significant loss of conductivity. The magnetic properties of nickel can be used to align the particles in unique patterns.
Spherical nickel powders
Type 4SP nickel powder is a high purity spherical nickel powder that is ideal for making powder metal parts when high sintered density and controlled shrinkage are important. Four size ranges are available.
Type 4SP-10 (-10 micron) powder is the preferred choice for the metal injection molding (MIM) industry. It mirrors the size and shape of the carbonyl iron powder used in MIM and therefore allows for uniform distribution throughout the alloy composition. Novamet also produces spherical powders SNP-20+10 (-20+10 micron), SNP+20 (+20 micron) and SNP-400 (-400 mesh) to give you a full range of particle sizes. Other fractions can be developed upon request.
Type HCA-1 nickel flake is the premier nickel product used in coatings for shielding electronic components against electromagnetic and radio frequency interference (EMI/RFI). It can be used in both solvent and waterborne paint formulations using acrylic, urethane or epoxy resins. Other applications include conductive inks, adhesives and anti-static floor coatings.
Nickel Flake Fine Leafing is an excellent binder for Tungsten Carbides as it disperses readily and uniformly coats the particles. In PTFE (Teflon) cookware coatings, it adds a metallic look while promoting abrasion resistance and heat transfer. It is also used in powder coatings and high temperature anti-seize lubricants. A Pigment Grade is available for use in specialty inks where a magnetic signature is desired.
Nickel Flake Fine Water can be used in waterborne coatings where its pewter-like appearance offers design alternatives. In silicone coil coatings, nickel flake promotes weld ability.
Nickel Flake CHT is used in high temperature, anti-seize lubricants.
Green Nickel Oxide is an ultra high purity nickel oxide containing 78.5% nickel with total trace elements typically less than 50 ppm. It is used in a variety of electronic applications including ferrites, thermistors, varistors and solid oxide fuel cells. Three versions are available, ranging in size from 1 to 15 microns.
