Aluminum alloy rolled plate and producing method thereof

Abstract

The invention relates to an aluminum alloy rolled plate and a production method thereof. The plate comprises the components of Si, Fe, Cu, Mn, Mg, Ni, Zn, Ti and Al. While in production, all components are mixed and melted at a temperature of between 750 and 770 DEG C, are subjected to slagging-off, refining and standing; and blank materials with the thickness of between 7.0 and 7.8mm are produced by casting and rolling; the thickness of the blank materials are rolled at an intermediate temperature to between 2.0 and 3.0mm by a four-high cold roll, and the blank materials are rolled into pattern boards or mirror boards; finally, the boards are subjected to stretch bending straightening and quenching. The boards in the invention are low in density and almost the same as aluminum in density, have the strength between 140 and 300MPa, and are strong in corrosion resistance; the rolled pattern boards are good in skid resistant performance, thereby meeting the use requirements of aluminum alloy floor boards in special fields(such as air planes); the aluminum alloy mirror boards have the advantages of stable performance, durability, light weight, good water proof and fire proof performances and wide application, and can be applied to indoor and outdoor decorations and lighting, etc. The method has the advantages of simplified process, low production cost and easy promotion and application.

Description

Aluminum alloy rolling plate and production method thereof 1. Technical field: The invention relates to an aluminum alloy plate and a production method thereof, in particular to an aluminum alloy rolled plate and a production method thereof. 2. Background technology: With the advancement of science and technology, aluminum alloy sheets are used more and more widely, not only in people's daily life, but also in industry, agriculture, construction, chemical industry, transportation, etc., and some are even used on space shuttles . For example, the current aviation aircraft has the advantages of high speed, high angle and high maneuverability during flight. In order to ensure the stability and safety of the aircraft, the aluminum alloy floor for aircraft has been proposed with light density, high strength, corrosion resistance, Anti-slip and anti-splashing water flow and other requirements. The invention patent with the application number 200710072126.X discloses an alumin...
