Contact rings made of ZlSr 60-40 alloy ‘Lux Aria’

Contact rings made of ZlSr 60-40 alloy ‘Lux Aria’ are products made of a gold-silver alloy of grade ZlSr 60-40. The composition and supply document have been verified against the manufacturer’s nomenclature catalog.

• Grade: ZlSr 60-40.
• Gold: 59.7-60.3% by mass.
• Silver: 39.7-40.3% by mass.
• Regulatory document: TU 48-1-318-87.

Dimensions, tolerances, delivery 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 change the technological behavior, mechanical and contact characteristics of the material, so similar names should not be substituted for one another. For this item, the composition and regulatory document are provided from a verified nomenclature source.

Selection of shape and execution

When ordering a semi-finished product, consider the grade, full composition, geometry, and delivery 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 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 the chemical composition. It must comply with the regulatory document and the customer’s design requirements.
