Abstract

The invention discloses a high-manganese aluminum bronze brazing alloy. The brazing alloy provided by the invention is composed of the following components in percentage by mass: 8.5-9.3% of Al, 8-11% of Mn, 1.5-3.0% of Ni, 2.0-4.0% of Fe, 0.05-0.25% of Ti, 0.02-0.10% of La, 0.02-0.15% of Y and the balance of Cu. The high-manganese aluminum bronze brazing alloy provided by the invention has enough strength and hardness and particularly good plasticity and impact toughness.

Description

technical field [0001] The invention relates to the field of brazing alloys, more specifically, relates to high manganese aluminum bronze brazing alloys with strong impact toughness and corrosion resistance. Background technique [0002] Aluminum bronze alloy solder has high strength, hardness, wear resistance and corrosion resistance. It is widely used in the surfacing and repairing of copper-aluminum alloy anti-corrosion pipe parts with the same composition, the connection of brass pipes, and the welding of marine propellers. Due to the high aluminum content of this solder, there are more brittle eutectoid phases (α+γ) in the structure. 2 ), the elongation rate is poor, the processing deformation hardening rate is extremely high, it needs repeated annealing and pickling to stretch to the finished product, the production efficiency is low, and the environmental pollution is serious. Contents of the invention [0003] The technical problem to be solved by the present inv...
