| PART NO. | DESCRIPTION | APPLICATIONS |
|---|---|---|
| AI-1800 | Nickel, 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-1804 | Machinable self-bonding Nickel based alloy. High bond strength and easy to apply. | Bearing journals, pump plungers, worn parts which cannot be ground. |
| AI-1805 | Iron-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-1820 | Nickel-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-1822 | Martensitic 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-1844 | 316 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-1850 | Spray-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-1855 | Austenitic 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-1860 | Spray-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-1866 | Low-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-1870 | Hardfacing 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. 53HRC | Applications up to 950°C involving corrosion, abrasion. |
| AI-1872 | A 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-1875 | AI-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-1888 | Aluminium 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-1892 | De-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-1893 | Pure Aluminium wire designed for arc spray. Self-bonding. | For atmospheric and marine galvanic corrosion prevention of steel structures. |
| AI-1894 | Pure Zinc arc spray wire. | For cheap protection of steel parts in-lieu of paint. Poor resistance to acidic corrosion. |
