Bimetallic barrel – Alloy Spec Sheet

Centrifugal casting bimetallic barrel uses high-speed rotation, so that the molten alloy and base metal are evenly coated in the tube.
TCB series bimetallic barrel, with high injection pressure and high strength alloy special base material, the strength is increased by 28%, and the pressure resistance can reach 490MPa.
Production range: TCB alloy layer is about 2.0mm~2.5mm, inner diameter Φ14~Φ190, length up to 3000mm
The applicable alloy types are as follows:
TCB-12: hardness 56~62HRC, wear resistance: good, corrosion resistance: normal, injection pressure resistance: excellent, glass fiber content: within 30%
TCB-20: hardness 62~68HRC, wear resistance: excellent, corrosion resistance: good, injection pressure resistance: super, glass fiber content: more than 30%
TCB-60: hardness 62~68HRC, wear resistance: good, corrosion resistance: super, injection pressure resistance: normal, glass fiber content: within 30%
TCB-90: hardness 60~66HRC, wear resistance: super, corrosion resistance: excellent, injection pressure resistance: excellent, glass fiber content: more than 40%
