DISPAL: A High-Performance Aluminum Material

10 Jan DISPAL: A High-Performance Aluminum Material

Aluminum is often referred to as the “green” metal thanks to its properties that support sustainable development. It is lightweight, strong, corrosion resistant, durable, versatile and impermeable – and also highly recyclable. These unique characteristics enable Gränges Powder Metallurgy to offer innovative and smart solutions for our customers. One result is DISPAL®, a range of high-performance spray-formed aluminum materials.

Due to spray-forming, a powder metallurgical process, the alloys solidify extremely quickly. This results in the material having an extremely fine grain and homogeneous micro-structure without inclusions or oxides. Whether light construction components for engines and gearboxes or semi-finished items for high-precision machinery, products made from our DISPAL® material ensure very good formability and weight reductions and a great number of performance enhancements. DISPAL® has properties comparable to those of steel but at only a third of its weight. It has dimensional stability comparable with steel and iron-casting alloys, resistance to wear and tear on the same level as cast iron alloys. The DISPAL® material offers customized thermal expansion rates, optimal wear and tear properties, high stability, and rigidity as well as very good heat dissipation and low weight in comparisons with other materials and technologies.

A remarkable combination of properties and benefits…

+ …high strength

+ …improved fracture toughness

+ …high temperature strength at working temperature up to 450°C

+ …high fatigue strength of 220 MPa by R=-1 and RT

+ …improved stiffness

+ …brilliant wear behavior (Hard Coat not necessary)

+ …adjustable coefficient of thermal expansion

+ …good thermal conductivity

+ …good forging and machinable

Our customers appreciate the variety of applications DISPAL® can be used for, for example:

  • Automotive Powertrain
  • Industrial robotics
  • High precision machinery
  • Aerospace
  • Satellites
  • Motorsport
  • Optical Industry
  • Defense
  • Metrology
