Title:
Ｓｎ含有銅合金及びその製造方法
Document Type and Number:
Japanese Patent JPWO2006016631
Kind Code:
A1
Abstract:
A fish cultivation net 3 has a rhombically netted form made by arranging a large number of waved wires 6 in parallel such that the adjacent wires are entwined with each other at their curved portions 6a. The wires 6 has a composition containing 62 to 91 mass% of Cu, 0.01 to 4 mass% of Sn, and the balance being Zn. The Cu content [Cu] and the Sn content [Sn] in terms of mass% satisfy the relationship 62 ¤ [Cu]-0.5[Sn] ¤ 90. The copper alloy material has a phase structure including an ± phase, a ³ phase, and a ´ phase and the total area ratio of these phases is 95 to 100%.
