Title:
BRASS TUBULAR MATERIAL AND BRASS SHEET MATERIAL
Document Type and Number:
Japanese Patent JP2001240926
Kind Code:
A
Abstract:

To improve the grindability of a brass material, particularly, of a brass tubular material and a brass sheet material by precipitating a γ phase, and also to keep its bending workability in a good characteristic value.

The occupancy area ratio of a γ phase is defined as 1 to 20%, or the average of the ratio between the major axis diameter and the minor axis diameter of the γ phase is defined as ≤11, or the average of the distance between the central points of the γ phase is defined as ≤25 μm, thus the brass material excellent in both grindability and bending workability can be obtained.
