ZlSrM 958-20 alloy wire

ZlSrM 958-20 alloy wire is a product made from the gold–silver–copper alloy system, grade ZlSrM 958-20. The composition and supply document have been verified against the manufacturer’s nomenclature catalog.

• Grade: ZlSrM 958-20.
• Gold: 95.8–96.3% by mass.
• Silver: 1.7–2.3% by mass.
• Copper: balance.
• Reference document: GOST 7222-75.

Dimensions, tolerances, supply condition, packaging, and batch volume must be agreed upon before ordering. For non-standard execution, confirmation of technical parameters is required.

Material features

Gold alloys are selected not only by gold content but also by the alloying system. Additives alter the technological behavior, mechanical, and contact characteristics of the material, so similarly named grades should not be substituted for one another. For this item, the composition and reference document are provided from a verified nomenclature source.

Choosing the form and execution

When ordering wire, the grade, full composition, geometry, and supply condition are considered. For wire, the diameter and length tolerances are critical; for foil and strip, thickness, width, and flatness; for solder, the preform shape and compatibility with the joining technology. Required parameters are specified in the specification.

Applications

The application area is determined by the combination of grade and product form. Gold alloys are used in electrical, contact, instrumentation, technological, and jewelry applications, but the specific purpose cannot be inferred solely from the chemical composition. It must comply with the reference document and the customer’s design requirements.
