Gold–tin solder PZlOl 78.5

Gold–tin solder PZlOl 78.5 is a product made from the gold–tin alloy system, grade PZlOl 78.5. The composition and supply document have been verified against the manufacturer’s catalog.

• Grade: PZlOl 78.5.
• Gold: 78.5±0.3% by mass.
• Tin: balance.
• Regulatory document: TU 48-1-385-90.

Dimensions, tolerances, supply condition, packaging, and batch size must be agreed upon before ordering. For non-standard configurations, 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 from a verified catalog source.

Choosing form and configuration

When ordering solder, consider the grade, full composition, geometry, and supply 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 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 the chemical composition. It must comply with the regulatory document and the customer’s design requirements.
