Jewelry clasp blank ZMK-585

Jewelry clasp blank ZMK-585 is a clasp blank for jewelry items. The nomenclature and supply document have been verified against the manufacturer’s catalog.

• Product type: clasp blank for jewelry items.
• Regulatory document: TU 9641-824-05785324-2006.

Dimensions, tolerances, supply condition, packaging, and batch size must be agreed upon before ordering. For non-standard versions, 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 regulatory document are provided according to a verified nomenclature source.

Selection of shape and version

When ordering a semi-finished product, 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 shape of the blank and compatibility with the joining technology. Required parameters are specified in the specification.

Applications

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

Processing and incoming inspection

Before processing, check the marking, geometry, surface, and accompanying documents of the batch. Forming, soldering, welding, or heat treatment modes are selected for the confirmed grade: transferring parameters from another alloy may alter the structure and result. The material is protected from contamination and mixing with other precious metals.
