Aluminium foam

 

ALUHAB is a new type of aluminum foam with controlled, homogeneous cell sizes which have a wide range of alloy compositions and attractive mechanical properties. The technology results in extremely stable liquid metal foams which can be cast into complex forms and re-melted without loss of foam integrity.

 

ALUHAB aluminium foams are manufactured from a special foamable aluminium alloy containing ultrafine particles below 3 microns. The technology uses special high temperature admixing technology to homogeneously disperse the particles and thus create a stable, foamable aluminium melt. Aluinvent’s unique loud-nozzle technology permits the injection of optimally sized bubbles into the melt from 10 to 0.5 mm range. The influence of alloy composition and cellular structure on the properties of aluminium foams can be characterized by X-ray tomography (CT), different analytical techniques and mechanical tests.

 

 

Advantages of ALUHAB:

  • Ultralight,
  • Energy absorption,
  • Adjustable density and properties,
  • Uniform and small cell size,
  • High specific strength,
  • Weldable,
  • Machinable,
  • Castable,
  • Corrosion resistant,
  • Non-flamable
  • Recyclable.

The tensile and compressive strength of 1 g/cm3 density ALUHAB aluminium foams can reach 40 to 80 MPa, while maintaining a 170 MPa flexural strength value.

Our aluminium foams are produced from different aluminium alloys on demand. Maximum block size is 50x180x1200mm³. The cell size can be varied between 0.5 and 20mm. Our products contain 2-50microns sized Al2O3 particles. Foam density depends on the cell size and varies between 0.2 and1.5g/cm³. Standard foamed alloys are AlSi10, 6061, 5052 and 7075. Semi-finished products having a desired geometry can also be produced from our foamed blocks.
