Method Of Manufacturing Aluminum Alloy Sheet

View page
US Patent:
58948791, Apr 20, 1999
Filed:
Aug 5, 1997
Appl. No.:
8/907105
Inventors:
Edwin James Westerman - San Ramon CA
Assignee:
Kaiser Aluminum & Chemical Corporation - Pleasanton CA
International Classification:
B22D 1112
B22D 11124
US Classification:
164476
Abstract:
A method for manufacturing aluminum alloy sheet including a continuous, in-line sequence of forming a strip of aluminum alloy and rolling the strip to reduce its thickness and to cool the strip sufficiently rapidly that precipitation of alloying elements is substantially minimized.

Method Of Producing Al-Zn-Mg Magnetic Memory Disk Substrates

View page
US Patent:
46996729, Oct 13, 1987
Filed:
Apr 28, 1986
Appl. No.:
6/856245
Inventors:
Edwin J. Westerman - San Ramon CA
Assignee:
Kaiser Aluminum & Chemical Corporation - Oakland CA
International Classification:
C22F 104
US Classification:
148 127A
Abstract:
Computer memory disk substrates which can be age hardened to a high yield strength after thermal flattening and yet are essentially free of magnesium silicide constituents detrimental to surface smoothness are prepared by replacing a portion of the magnesium usually includes in high amounts as an alloying element with zinc.

US Patent:
56555938, Aug 12, 1997
Filed:
Sep 18, 1995
Appl. No.:
8/529644
Inventors:
Edwin James Westerman - San Ramon CA
Assignee:
Kaiser Aluminum & Chemical Corp. - Pleasanton CA
International Classification:
B22D 1112
B22D 11124
US Classification:

Clad Magnetic Memory Disk Substrate

View page
US Patent:
47228725, Feb 2, 1988
Filed:
Apr 28, 1986
Appl. No.:
6/856244
Inventors:
Edwin J. Westerman - San Ramon CA
Assignee:
Kaiser Aluminum & Chemical Corporation - Oakland CA
International Classification:
B32B 1520
C22F 104
US Classification:
428654
Abstract:
A magnetic memory disk substrate which maintains a high degree of surface smoothness together with high yield strength is prepared by cladding a core material with a cladding layer containing a maximum of about 3% magnesium. The core material is aluminum alloyed with one or more elements such as zinc, magnesium, copper and silicon to produce an improved yield strength. The cladding comprises from about 3% to about 10% per side of the thickness of the entire composite and generally contains further alloying elements for enhanced corrosion resistance. Silicon impurities generally amount to less than 0. 5%.
