摘要:
An aluminum alloy with freely-machinable or free-cutting properties and corrosion resistance consists essentially of aluminum, copper, magnesium, tin, lead, and silicon and optionally further contains small amounts of any one or more of the elements selected from chromium, manganese, titanium, vanadium and zirconium. This alloy has the property for preventing peeling-off of an anodically oxidized surface layer after being heated at an elevated temperature.

A high strength, aluminum alloy sheet having good formability is disclosed which is particularly suitable for forming can-body parts and can-end parts, which sheet has received a final cold rolling reduction of at least 50% and consists essentially of Mn 0.30 to 1.50 wt. %, Mg 0.50 to 2.00 wt. %, preferably 0.50 to 1.25 wt. %, Si 0.52 to 1.00 wt. % and the balance being Al and incidental impurities. If required, the aluminum alloy forming sheet may also, in addition to the above elements, contain at least one component selected from the group consisting of Fe, Cu, Cr, Zn and Ti in specified ranges.The alloy sheet was produced by a specially prescribed production method.
摘要:
The fin stocks for use in a heat exchanger made of aluminum alloy are made by use of an aluminum alloy having a sacrificial anode effect so that the fluid passage members of the heat exchanger are protected from corrosion electrochemically. A method for producing an aluminum alloy for use in the fin stocks is disclosed with the analysis of the function of each component of the aluminum alloy and determination of the ratio of each component in the alloy.
摘要:
The present invention relates to a cold-rolled aluminum-alloy sheet having a high strength and a good formability required for producing a DI can. The sheet according to the present invention contains 0.1-2.0% Mn, 0.1-2.0% Mg, and 0.1 to 0.5% Si, has a thickness of 0.4 mm or less. The present invention is characterized by holding a sheet to a temperature of from 80.degree. to 150.degree. C., when it is already heat treated at 400.degree.-580.degree. C. and it is not yet finally cold-rolled. The sheet according to present invention is finally cold-rolled and has a fine grain size.

A brazing method is disclosed which provides superior strength in the brazed joint formed. The brazed structure is subjected to a heat treatment after brazing, which improves the strength of the joint even if Magnesium compounds are employed.
摘要:
An aluminum alloy of age-hardening type indispensably containing copper, magnesium and silicon, being optionally added thereto traces of any one or more than one element selected from vanadium, manganese, chromium, zirconium and titanium.A sheet or strip made from said alloy ingot, being submitted to solution treatment followed by precipitation process can improve forming properties, such as tensile strength, LDR and/or earing ratio, and be free from stretcher-strain marks.Said sheet or strip maintains high strength particularly when it is submitted to baking i.e. high temperature curing of paint coated thereon.
摘要:
A synthetic chloroprene rubber adhesive composition which contains carboxylated synthetic chloroprene rubber for the main ingredient thereof and further contains chlorinated polypropylene and/or a chlorinated polypropylene derivatives. The adhesive composition can strongly bond various components to polypropylene used for a speaker frame, etc. unlike conventional synthetic chloroprene rubber adhesives which have insufficient adhesion strength in this application.
