The invention provides a beryllium bronze alloy for an ABS sensor bush, which belongs to a novel beryllium bronze alloy material and comprises the components by weight percent: 1.8% to 2.5 % of beryllium, 0.15% to 0.3% of cobalt, 0.01% to 0.05% of aluminum, 0.01% to 0.05% of iron, 0.001% to 0.01% of nickel, 0.01% to 0.1% of zinc, less than 0.001% of inevitable impurity and the balance of Cu. The alloy material with high intensity and high elasticity is made by regular material preparation, material mixing, melting, casting and cold and thermal processing. The tensile strength sigma b is from 830 to 860MPa, the hardness HV is from 394 to 398, the extension rate delta s is from 2% to 3% and the elasticity modulus E is from 128 to 130GPa. The beryllium bronze alloy material is mainly used formaking the ABS sensor bush, can be also used for making various welding electrodes in resistance welding machines, various mould embedding pieces and other elastic elements and has excellent physicaland mechanical performance and favorable economic benefit.
