SA701 Details
High functional composite material in which SiC ceramic particles are uniformly impregnated with Al.
Features
With physical properties similar to ceramics and can be made into large size.
SA701→Support size over 1.5m × 1.5m
Ceramics limit Al2O3,SiC 1m×1m
*Relative to our company
High fracture toughness 8 MPa･m1/2
Create high fracture toughness ceramics by mixing
metals with ceramics (overcoming fragility).
Excellent thermal properties
Low thermal expansion→Lower than Aluminum,Iron : 7 x10-6/K
High thermal conductivity→Higher than SiC : 160 W/m･K
