2023-04-27 00:12:36

First, the Japanese non-ferrous metal brand representation

The Japanese JIS standard number consists of JIS, letter type number, number type number, serial number and year of formulation. Grades consist essentially of material category letter codes, digit groups, and product shape codes. Refer to the following tables for the designation of the grades of metal materials, product shape codes, and the status codes for copper and aluminum materials.

Instructions

Pure aluminum

A+4 digit group + product shape code

Example: A1080P, A1N30H, A2N01

A - Aluminum and aluminum alloys, on the front digit 1 indicates industrial pure aluminum; the second digit indicates the number of controlled impurities, if N, then it is the original alloy of Japan; the third and fourth two digits indicate pure The aluminum degree percentage is two digits after the decimal point. The product shape code is shown in the following table

Aluminum alloy

A+4 digit group + product shape code
