Stamped blank for watch case from ZlSrM 585-80 alloy

Stamped blank for watch case from ZlSrM 585-80 alloy — a product made of gold–silver–copper alloy grade ZlSrM 585-80. Composition and supply document are verified against the manufacturer’s nomenclature catalog.

• Grade: ZlSrM 585-80.
• Gold: 58.5–59.0% by mass.
• Silver: 7.5–8.5% by mass.
• Copper: balance.
• Regulatory document: TU 1995-804-05785324-2005.

Dimensions, tolerances, supply condition, packaging, and batch volume must be agreed 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 alloying system. Additives change the technological behavior, mechanical and contact characteristics of the material, so similar-sounding grades should not be substituted for one another. For this item, composition and regulatory document are given according to a verified nomenclature source.

Choice of shape and execution

When ordering a semi-finished product, consider the grade, full composition, geometry, and supply condition. For wire, diameter and length tolerances are critical; for foil and strip, thickness, width, and flatness; for solder, the shape of the blank 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 shape. Gold alloys are used in electrical, contact, instrumentation, technological, and jewelry applications, but the specific purpose cannot be inferred from chemical composition alone. It must comply with the regulatory document and the customer’s design requirements.
