What main categories does precision alloy include?

Precision alloys fall into four core branches classified by functional characteristics. Soft magnetic alloys feature high permeability and low coercivity for electromagnetic conversion components. Low-expansion alloys maintain nearly unchanged size with temperature shifts to avoid assembly deformation. Elastic precision alloys own stable modulus and fatigue resistance for tiny sensing springs. Resistance alloys keep consistent resistivity under temperature variation for precision circuit resistors. Each type has customized element ratios and processing standards to match exclusive high-precision working scenarios without cross substitution in critical equipment.
