铍铜合金是一种以铍为重要元素的高弹性高导电性合金材料，主要用于要求高可靠性的精密仪表、电子、电器等领域。近几年来随着全球经济的持续增长，特别是计算机、移动电话的快速发展，为铍铜合金的生产和开发带来了广阔市场。1998年，日本铍铜轧制材的需求量每月为170t~180t； Beryllium copper alloy is a kind of high elasticity and high conductivity alloy material taking beryllium as an important element, and is mainly used in the fields of precision instruments, electronics and appliances requiring high reliability. In recent years, with the continuous global economic growth, especially the rapid development of computers and mobile phones, it has brought a vast market for the production and development of beryllium-copper alloy. In 1998, the demand for rolled beryllium copper in Japan was 170t-180t per month;
