Dimensions, tolerances, delivery condition, packaging, and batch size must be agreed 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 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 specification are given per a verified catalog source.

Choosing form and configuration

When ordering foil, 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 preform and compatibility with the joining technology. Required parameters should be 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 from chemical composition alone. It must comply with the specification and the customer’s design requirements.
