Containing 50% chromium carbide. The alloy may provide up to two times the life of Ultrachrome® A05 alloy

Hypereutectic white iron, suitable for high wear duties. Can effectively be used in the alumina industry, mill discharge applications and tailings pumps, offering a significant life advantage over conventional erosion resistant alloys

A14

ULTRACHOME Tough 27% Cr

Alloy A14 is a high chromium white cast iron offering high impact resistance and moderate erosion wear resistance. Alloy A14 is suitable for gravel pump applications where large slurry particles are present. A14 is much tougher than A05 but also exhibits a lower erosion wear resistance.

R55

Nature Rubber

• Standard elastomer offering for erosive applications

• Premium natural rubber that offers resistance to shear and tearing from hard particle slurries

• Particularly suited for large particle erosive slurry applications such as mill discharge

U38 and 566

Polyurethane

• Erosion resistant polyurethane material with high tear resistance and tensile strength

• Utilized in fine particle slurries such as sand or applications requiring tip speeds beyond limits of R55® rubber

• Most suited for tailings, flotation, leach duties, and applications where “tramp” is a problem

 Linatex Rubber

• Linatex rubber is rated as 37 on the IRHD scale of elastomer hardness. This equates to a rubber that is soft and flexible.

• Superior Abrasion Resistance: Linatex rubber demonstrates advanced mechanical properties that provide superior

abrasion resistance and unmatched performance in wet conditions compared to other types of rubber.

• Lower Total Ownership Costs; Reduced Downtime Compared to other rubber products, Linatex® rubber has

Demonstrated superior performance in operating mines and has shown significant lower total ownership costs. Linatex

natural rubber lining pays for itself over and over again.

SiCEP

SiC Ceramic

• offer exceptional wear resistance due to silicon carbide's extreme hardness, making them ideal for abrasive slurries.

• provide superior corrosion resistance, handling acids, alkalis, and harsh chemicals better than other material.

• With high mechanical strength and thermal stability, they ensure long service life and reliability in demanding industrial

applications.

SiN+Sic Ceramic

• Possessing all the characteristics of SiC ceramics, it is more suitable for handling slurries with large amounts of highly

abrasive particles than SiC ceramics.

A05+SiC Ceramic

A3+Sic Ceramic

QT500-7+SiC Ceramic

• It is wear-resistant and corrosion-resistant, and its service life is 3 to 10 times that of common chromium alloy and stainless steel.
