The performance characteristics of high temperature resistant aluminum foam

For example, the operating temperature range of ALMAG alloy is 560～640℃, but the foam of ALMAG alloy The alloy does not dissolve when heated to 1400°C in the atmosphere.

Through the stress-strain test of this material, it is found that its strain strongly lags behind the stress, and the compressive stress-strain curve contains a long smooth section, so the high temperature resistant aluminum foam is a kind of high impact energy absorption characteristics. 

Therefore, the greater the porosity, the greater the conductivity. Thermal physical properties High temperature resistant aluminum foam generally has high heat resistance, and does not dissolve even if the temperature reaches the melting CASCELL® HF foam point of the base alloy. The impact energy absorption characteristics of high temperature resistant aluminum foam material has a unique network, non-directional porous structure, and no rebound effect .

High temperature resistant foam'The performance characteristics of high temperature resistant aluminum foam: light weight, low density; mechanical properties, high temperature resistant aluminum foam has lower tensile strength and lower specific strength, but higher compressive strength and bending strength 

The tensile strength is only about 1/100 of that of aluminum, and the specific strength is about 1/10 of that of aluminum. Therefore, the ratio of aluminum to pores on the cross section determines the conductivity of the foam material. Permeability Permeability is another characteristic of through-hole aluminum foam. For example, high-temperature resistant foamed aluminum does not have the ductility of aluminum and almost no plastic deformation occurs under pressure
