Small density, low modulus of elasticity, small thermal conductivity, close to tensile strength and yield strength, non magnetic non-toxic, strong damping resistance, good heat resistance, good low temperature resistance, corrosion resistance, air suction performance (gas storage, drying)
High strengthhigh thermal strength
good corrosion resistance
low temperature performance
high chemical activity
little heat conduction elasticity
good toughness
plasticity and high temperature deformation
