Abstract

The invention discloses a method for manufacturing water meter housing by high strength cast aluminum alloy and a product thereof. The manufacture adopts the aluminum alloy with 3.00-11.50 percent of Cu, 0.15-3.50 percent of Si, 0.15-2.50 percent of Mg, 0.20-1.20 percent of Mn, 0.15-0.25 percent of Ti, 0.03-0.10 percent of B, 0.05-0.10 percent of RE, 0.01-0.1 percent of Sr, 0.001-0.005 percent of Be, and rest of Al to manufacture the water meter housing with a casting method. The water meter housing manufactured by the invention has the advantages of high strength under high temperature, light weight, low cost and energy saving.

Description

technical field [0001] The invention relates to a method for manufacturing a water meter shell by high-strength cast aluminum alloy and its products. Background technique [0002] The water metering case has always been made of cast iron and cast brass. These two types of case materials always have the problem of heavy case and secondary pollution caused by corrosion products, especially the leaded brass case has high cost and Serious lead pollution problem. On the other hand, the development of aluminum alloys with light weight, low cost and suitable for casting can meet the harsh working environment and mechanical performance requirements of water meters, and will overcome the problems and shortcomings of the aforementioned two materials for water meter cases. [0003] In Chinese patent applications 200810177309.2 and 00910000646.9, the applicant disclosed two types of casting aluminum alloy manufacturing methods for water meter cases and products thereof. Among them, th...
