Metal Types

IXL Metal Castings Pty Ltd manufactures in a range of metal types to match its capabilities with customer needs. The following summarises the most generally used metal types with an indication of the benefits of each.

Grey Iron (alloy)

Named due to the colour of its “fracture”, it is made in various heat resistant and tensile grades as well as different hardness levels depending on customer requirements and end use. Some of the major uses of gray iron include brake discs, engine blocks and general engineering type products.

Ductile Iron (Nodular or Spheroidal Graphite Iron)

Used in situations where a high tensile strength and ductility are required. Some of the typical applications of ductile iron include molten metal siphon bodies, large butterfly valves, yokes and brick moulds. High tensile products are typically hard and also have superior wear resistance for jobs where this is critical.

Ni-Resist

It is primarily used in circumstances where chemical resistance is required to extend product or equipment life. The types of products would include mixing paddles exposed to highly corrosive substances.
The combination of properties in Ni-Resist, also give performance and cost advantages over steel in the manufacture of valves. Industries such as petrochemical, pulp and paper, chemical and power plants would traditionally be major users.

Ni-Hard

A nickel – chromium white iron, primarily used where outstanding abrasion resistance is required but which also has strong corrosive resistance. It is used extensively in the mining, power, cement, paint, dredging and foundry industries. Typical applications include mill liners, pulverizing rings, slurry pump parts and pipes and elbows.

Stainless Steel

Corrosion and heat resistant material used primarily for smelter crust breakers and pump liners where reconditioning is seen as more cost effective than total replacement.
