Engineering Materials

Engineering Materials comprising of Tungsten based products, for three principal areas of application :

Mallory products have widespread acceptance in the aerospace industry. The high density of these materials (up to 55% greater than that of lead) enables the volume of balancing masses to be minimised.

Individual applications include:

vibration damping and dynamic balancing

centrifugal balancing

flywheels and balance weights

governor weights

missile and fuselage mass balancing

riveting dollies and bucking bars

accelerometer and transducer components

Mallory Heavy Alloys are used to provide protective shielding in radiotherapy units, radiographic equipment and isotope containers.

These Heavy Alloys are about 50% more effective in shielding against gamma- and X-radiation than lead and can, therefore, provide the same degree of protection as lead whilst significantly reducing the overall volume and thickness of shields and containers.

Mallory products are used in critical applications found within the metal processing industry.

Extrusion Dies
Mallory 4000 to 4200 are products widely used for the dies employed in the extrusion of metals, especially copper based alloys, because they last longer than traditional die materials.

The benefits of Mallory products are:

reduction in press down-time

excellent crack resistance

minimal extruded metal pick-up

high thermal stability

high impact resistance

good machinability

Spark Machining Electrodes
In electrical discharge machining (EDM), the use of Mallory 10W3 ensures maximum electrode life and minimum down-time.

Die casting Components
Mallory products are used in die casting tooling, particularly in the manufacture of aluminium, zinc and brass castings, to ensure the long die life and minimum shrinkage proosity of the components.

Tool Shank Material
Compared with conventional boring-bar materials, Mallory No-Chat allows a greater length of shank, or a greater depth of cut, before chatter sets in. The density and strength of Mallory No-Chat, and its excellent vibration-damping property make it ideal for supporting abrasive wheels working at high speeds, allowing faster grinding of deep holes with improved finish and closer tolerances.
