METAPOR® HD 100 AL is available in four standard sizes: 500L x 500W x 15/20/30/60 mm, (~19.7″ x 19.7 x 0.6/0.8/1.2/2.4″), and is cut into slabs of any required thickness. After the cutting process, the air permeability of the slab surface is reduced due to partial closure of the pores. It is essential to mill both surfaces of the slab by cutting off approx. 0.25 mm, (0.010″), providing complete air permeability.
Store dry and flat to protect against jolts, impacts and bowing. Avoid contact with grease and fluids.
The machining properties of METAPOR® are excellent and are comparable with rapid machinable aluminium. METAPOR® must be machined dry and should not be in contact with any cooling liquids. In order to avoid any closure of pores, appropriate aluminium cutting tools must be used. It is recommended to use dust extraction. Avoid contact with grease and fluids.
Grinding and polishing of the machined surfaces can be made by hand or with a vibrating grinder. Use corundum paper with grains of 400 / 600 / 1200 in ascending order. METAPOR® must be polished dry and without any polishing paste!
Air Flow Rates
The numbers are average values for calculating air consumption for overpressure or under pressure applications. Specification is in liters per minute per cm2.
