We are an exclusive manufacture in producing Continuous Cast Iron Hollow Bar which is..
A high quality alternative to castings due to:
No porosity, slag, shrinkage or other typical casting defects
Dense, fine-grained microstructure
Thin wall tube Min. 7mm only
No pattern or tooling costs
An excellent cost-saving alternative to low-medium carbon steel because of:
Better machinability - up to 3 times faster with better chip control (no more long, tangled, sharp chips)
Minimized deburring
Longer tool life
Improved wear resistance
10% lighter weight
Quieter due to vibration damping
30-70% material saving compare with solid bar for hollow parts
Machined parts in these and other industries are already benefiting from Tongxin material advantages:
Fluid Power --Oil & Gas—Industrial—Defense--Primary Metals--Automotive Aftermarket
