Contact Ring Blanks from Alloy ZlSrM 58.5-8

Contact ring blanks from alloy ZlSrM 58.5-8 are products made from a gold-silver-copper alloy grade ZlSrM 58.5-8. The composition and supply document have been verified against the manufacturer’s catalog.

• Grade: ZlSrM 58.5-8.
• Gold: 58.2-58.8% by mass.
• Silver: 7.5-8.5% by mass.
• Copper: balance.
• Reference document: TU 117-1-800-92.

Dimensions, tolerances, condition of supply, packaging, and batch size 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 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 catalog source.

Selection of Form and Execution

When ordering a semi-finished product, consider the grade, full composition, geometry, and condition of supply. For wire, diameter and length tolerances are critical; for foil and strip, thickness, width, and flatness; for solder, the form 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, but the specific purpose cannot be inferred solely from chemical composition. It must comply with the reference document and the customer’s design requirements.
