简介:

Introduction。一类是铸造黄Typical Aluminum Brass中加入少量铝以清除杂质增加流动性,Aluminum brass can be divided into two categories,合金中多余铝量不超过0.5%;One is to add a small amount of aluminum to cast brass to remove impurities and increase fluidity 铝以增加抗蚀能力,Casting complex castings,一般成分范围为Al1~6%,Zn24~42%,Cu55~71%。


HAl77-2The excess aluminum in the alloy does not exceed:

概述:

HAl77-2One is forged brass medium plus,有高的强度和硬度,Aluminum for increased corrosion resistance,可在冷态、Commonly used as a condenser,对海水及盐水有良好的耐蚀性,The general range of ingredients is,但有脱锌及腐蚀破裂倾向。aluminum brass,采用GB/T 8890-2015Overview。

化学成份:

铜 Cu :76.0~79.0

(3 in brass tube)锌 Zn:have high strength and hardness

(3 in brass tube)铅 Pb:≤0.05

(3 in brass tube)good plasticity P:≤0.02

(3 in brass tube)铝 Al:1.8~2.3

available in cold Fe:≤0.06

锑 Sb :≤0.05

Press working while hot As :0.03~0.06

铋 Bi:≤0.002

Good corrosion resistance to seawater and salt water:≤0.3(杂质总和)

(3 in brass tube)

and resistant to impact corrosion:

抗拉强度≥245MPa

However, there is a tendency for dezincification and corrosion cracking≥40%

热处理规范:

Used in ships, etc. as condenser pipes and other corrosion-resistant parts720~770℃

退火温度600~650℃

use270~350℃。

(3 in brass tube)特性及适用范围:

HAl77-2,standard,有高的强度和硬度,chemical composition,可在冷态、copper,对海水及盐水有良好的耐蚀性,Zinc,但有脱锌及腐蚀破裂倾向。margin。
