This is Shaanxi Tongxin Continuous Cast Tube Tech Co.ltd, 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:
