Thermoelectrode wire from ZlZh 999 alloy

Thermoelectrode wire from ZlZh 999 alloy is a product made of a gold-iron alloy of grade ZlZh 999. The composition and supply document have been verified against the manufacturer’s nomenclature catalog.

• Grade: ZlZh 999.
• Gold, not less than: 99.9% by mass.
• Iron: 0.02±0.005% by mass.
• Regulatory document: TU 48-1-248-85.

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 grades with similar names should not be substituted for one another. For this item, the composition and regulatory document are provided according to a verified nomenclature source.

Selection of form and execution

When ordering wire, the grade, full composition, geometry, and delivery condition are considered. For wire, the 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 the chemical composition. It must comply with the regulatory document and the customer’s design requirements.
