Gold Delight blank from alloy AuAgNiZn 750-150-7.5

«Gold Delight» is the catalog name for a high-readiness jewelry blank made of gold alloy. The product is identified by the grade AuAgNiZn 750-150-7.5 and the supply document.

What this item is

This is not a finished piece of jewelry with a predetermined geometry. The TU defines the type of supply, while the shape, mass, dimensions, allowances, and degree of readiness of a specific execution must be obtained from a drawing or specification. The series name does not replace the technical designation of the alloy.

Composition and documents

• Grade: AuAgNiZn 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
• Supply document: TU 9641-823-05785324-2005

The grade AuAgNiZn 750-150-7.5 belongs to the gold–silver–nickel–zinc system. The composition confirms the presence of nickel and zinc, but by itself does not specify hardness, color standard, dimensions, or part readiness. These indicators depend on the supply condition and technology. The actual batch is accepted according to the quality document.

Applications and technological role

• blank for further jewelry processing per an agreed drawing;
• finishing, assembly, and polishing operations after checking allowances and surface condition;
• small-batch production where the material and mass of each item are confirmed by the batch certificate;

What to agree before ordering

Specify the required geometry, mass or mass range, tolerances, surface condition, batch size, and acceptability of subsequent soldering. Request the execution drawing, quality document with actual composition, marking and packaging information. Separately confirm that the catalog name «Gold Delight» corresponds to the desired variant.

Safety and handling

The alloy contains nickel: avoid dust generation and prolonged contact of contaminated surfaces with skin. Use local exhaust ventilation, eye protection, and gloves; PPE requirements should be confirmed via the safety data sheet. When soldering, control flux fumes and hot parts. Store chips and dust separately.
