TS 4818

TS 4818 is a terminology standard for castings made from copper and copper alloys. Standards of this kind help ensure that the same technical terms are understood consistently across design, production, inspection, and purchasing contexts; here, the focus is specifically on the naming and definition of casting-related concepts.

Why castings are treated as a distinct terminology set

Casting is the process of pouring molten metal into a mold so it solidifies into the required shape. In copper and copper alloys, castings are used where properties such as corrosion resistance, electrical conductivity, thermal conductivity, and machinability are important. Separating the terminology for cast products helps avoid confusion with other copper product forms and supports precise technical communication.

What this standard covers

According to the supplied scope, the standard covers terms and definitions for copper and copper alloy castings. In other words, it defines the vocabulary for this specific product family rather than for wrought products, semi-finished forms, or unrelated metal groups. Its equivalence to ISO 197-4:1983 indicates alignment with an established international terminology framework.

• It is a terminology-based standard, aimed at consistent technical language and reduced ambiguity.
• It focuses on castings made from copper and copper alloys.
• It addresses both the terms themselves and their definitions.
• It sits within the broader fields of metallurgical terminology and copper alloy classification.
