What are precision alloys?

Precision alloys are a specialized series of metal materials with strictly controlled chemical compositions and precisely calibrated physical properties, developed to meet ultra-high precision industrial demands. They mainly consist of iron, nickel, cobalt and chromium matrix systems, divided into soft magnetic, low-expansion, elastic and resistance types. Unlike regular structural steel, their magnetism, thermal expansion rate, elasticity and resistivity stay stable amid temperature changes, vibration and long continuous operation. Every production link adopts tight tolerance control to eliminate property deviation, serving as core functional parts for precision electronics, measuring instruments and aerospace control systems.
