Strips of Gold-Silver-Nickel-Zinc Alloy ZlSrNC 750-150-7.5

Strips of ZlSrNC 750-150-7.5 alloy — products made from the gold–silver–nickel–zinc alloy grade ZlSrNC 750-150-7.5. Composition and supply document verified against the manufacturer’s catalog.

• Grade: ZlSrNC 750-150-7.5.
• Gold: 75.0–75.5% by mass.
• Silver: 14.5–15.5% by mass.
• Nickel: 7.0–8.0% by mass.
• Zinc: balance.
• Reference document: GOST 7221-80.

Dimensions, tolerances, delivery condition, packaging, and batch size 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 alter the technological behavior, mechanical and contact characteristics of the material, so similar grades should not be substituted for one another. For this item, composition and reference document are provided from a verified catalog source.

Choosing Form and Execution

When ordering strips, consider 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 form 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 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.
