Copper Bellows:
1) Balances and compensates to prevent displacement or vibrations in extreme temperatures, pressure, or thrust.
2) Used extensively in all facets of the high-tech steel industry as well as other industries.
3) Have good flexibility and handle extreme temperature and pressure well.
4) They can play an important role in hose reciprocating motion, thermal expansion absorption, vibration absorption and adjusting compound tube center.

Metal bellows is widely used in automatic controlling and measuring instrument , vacuum technique , mechanical industry , power industry , transportation and other industry , as sensitive element , damping element  , compensating component , valve component .
