FAQs that can help you in this category
For foundry moulds Final Advanced Materials produces alumina, silicon carbide, silica or zirconia-based cements, which are suited for temperatures between 1,200 and 2,200°C. Zirconia formulations are particularly suitable if a very high resistance to chemicals is required. Alumina cements have better mechanical resistance (>40 MPa in compression). SiC cement is a very good option for molten metal casting, launders, crucibles or nozzles. The choice depends on the cast metal and the temperature (e.g.: aluminium ~700°C, steel >1,500°C) and the thermal shock resistance.
The choice depends mainly on the temperature and the mechanical stresses.
Final Advanced Materials' high-temperature epoxy resins are generally limited to temperatures ranging between 150 and 350°C, have a good mechanical resistance (typical sheer-stress 10–30 MPa) and a degree of elasticity.
However, the ceramic cements produced by Final Advanced Materials can be used up to 2,200°C, depending on the grade (alumina, zirconia, silicon carbide, silica). They have excellent temperature resistance, but remain fragile (brittle behaviour, no elasticity).
Environmental constraints are important factors which must also be taken into account.
