N-FLAT Nippon Light Metal Company, Ltd.

N-FLAT

N-FLAT is a rolling-nished 5000 aluminum alloy plate. Its advanced high-precision property helps to reduce customers’ processing costs for cutting component parts such as semiconductor manufacturing equipment and LCD manufacturing equipment.

Features

Ensures thickness tolerance approx. ±0.8 or less.

Major thickness plates ensure surface flatness 0.4～0.5mm/M.

Greatly reduced residual stress over conventional products.
