Materials
We offer sand casting with both ferrous and non-ferrous materials, including
aluminium alloys, brass alloys, bronze alloys, steel, carbon steel, high tensile
steel, stainless steel, grey iron, spheroidal graphite iron.
Tolerances
Sand casting tolerance is influenced by the casting material and its structure, the
grade of the Sand Casting tolerance will be CT9 ~ CT11.
