PART NO.DESCRIPTIONAPPLICATIONS
AI-1800Nickel, Moly Aluminium superbond wire developed specifically for its high bond characteristics. 76MPa bond strength on blasted surface.As a bond coat under other thermal spray coatings onto any substrate.
AI-1804Machinable self-bonding Nickel based alloy. High bond strength and easy to apply.Bearing journals, pump plungers, worn parts which cannot be ground.
AI-1805Iron-based self bonding alloy with outstanding corrosion resistance and good machineability. 30% Chrome.Boilers, heat exchangers, petrochemical industry, pump housings, pulp and paper industry.
AI-1820Nickel-Chrome corrosion resistant coating, self bonding. Can be used as bond coat where applications don’t allow aluminium. Machineable.Thermal barrier coatings, corrosion resistant coatings up to 982°C
AI-1822Martensitic 420 high chrome stainless steel coating. Produces a hard, dance coating with excellent wear resistance. Difficult to machine. Requires bond coat.Bearing journals, hydraulic rams, pistons, bearing housings.
AI-1844316 Stainless steel wire designed specifically for arc spraying. Easy flowing wire. Requires bond coat.Any application providing a coating of corrosion resistant 316 stainless.
AI-1850Spray-and-fuse wire. Designed for subsequent fusing after application. Produces metallurgically bonded deposit with high wear resistance. Post fusing coating must be ground. 50-55HRC.Applications involving severe high stress abrasion combined with low impact at temperatures not exceeding 450°C.
AI-1855Austenitic spray wire made exclusively for arc spraying. Excellent corrosive properties and machineable.Where dense, corrosion resistant coatings are required. Seal rings, gland casings, valve plugs etc.
AI-1860Spray-and-fuse wire. Designed for subsequent fusing after application. Produces metallurgically bonded deposit with high wear resistance. Post fusing coating must be ground. 60-62HRC.Applications involving severe high stress abrasion combined with low impact at temperatures not exceeding 450°C.
AI-1866Low-shrink wear resistant steel wire made exclusively for arc spraying. Unlimited coating thickness without cracking. 220HB. Fully machineable.Bearing journals, shafts, any application requiring a wear resistant machineable coating.
AI-1870Hardfacing alloy designed exclusively for arc spraying. Hard, abrasive and wear resistant coating. Work hardens in service. Impressively tough for a coating this hard. Finish by grinding only. Requires bond coat. 53HRCApplications up to 950°C involving corrosion, abrasion.
AI-1872A self-bonding hardfacing alloy designed exclusively for arc spraying. Reduces overall coating cost by elimination of bond wire. Requires bond coat. Work hardens in service up to 53HRc.Applications up to 950°C involving corrosion, abrasion.
AI-1875AI-1875 is a solid Nickel Aluminium bond wire produced specifically for metal spraying. It has been introduced as an economical alternative to AI-1800 bond wire where ultimate bond strength may not be required. AI-1875 can be finished by either machining or grinding. It can be applied directly on to a smooth, chemically cleaned surface where rough machining or grit blasting is not possible. It is recommended however, that a Class 2 white finish be achieved prior to spraying, by grit blasting with a Chilled Iron G24 grade grit or rough machined to maximise bond strength.
AI-1888Aluminium Bronze wire made exclusively for arc spraying. Self-bonding alloy.Reclaiming bronze components, protective layers on cast iron and unknown steel components, bearing journals and housings. Corrosion resistant applications.
AI-1892De-oxidised copper wire made exclusively for arc spraying. Excellent thermal and electrical conductivity. Requires bond coat.Applications requiring good thermal conductivity including dies, carbon brushes, discharge electrodes, earthing conductors
AI-1893Pure Aluminium wire designed for arc spray. Self-bonding.For atmospheric and marine galvanic corrosion prevention of steel structures.
AI-1894Pure Zinc arc spray wire.For cheap protection of steel parts in-lieu of paint. Poor resistance to acidic corrosion.
