Brief introduction:
3J53 is a constant elastic alloy, which can obtain high elasticity and strength after aging, has a low modulus of elasticity temperature coefficient in the range of -60-100 °c and is resistant to corrossion.
It's used for manufacturing diaphragms, bellows, bellows, springs and other elastic components in the instrument industry.
