This study successfully demonstrated the overall advantages of multistep anodization of heat-treated wrought aluminum alloy AA7075-T6 that is a widely used in aerospace, automotive and fracture-critical applications.
The chemistry of the “no-dump” caustic etch bath is complex. There are several chemical reactions that take place at different levels of constituent concentrations and temperatures.
ALMAG Aluminum is bringing a former aluminum extrusion and anodizing facility in Pennsauken Township, New Jersey, back to life, revitalizing and rejuvenating over 163,000 square feet of the New Jersey complex.
Using multi‐component dye baths in anodization processing can be a frustrating endeavor when not equipped with a basic understanding of color theory and how different dyes are affected by various factors.
Blistering of the anodic coating on 7075 alloy parts is a common but elusive problem that many anodizers face.
Danco Medical, part of the Lincotek Group, will launch a second production site in Warsaw, Indiana, early in 2024 to add capacity in aluminum anodizing and deep image graphics.
Three years ago, Andrew Kossowski left the corporate world behind to buy a metal finishing operation. This year, he is building himself a new one.
Structural comparison and chemical analysis of various types of anodic aluminum oxide (AAO) finishes produced from conventional electrolytes and those produced from an electrolyte modified with electroactive polymer determined differences, which explain superior bonding performance by the AAO produced from the modified electrolyte.
Simon Haining is two years into his new job as president of High Tech Finishing in Houston, but one thing he has quickly learned is to listen to the customer.
A cold seal — also known as a room-temperature seal — is a sealing bath that contains nickel and fluoride and is used at ambient temperatures.
Suffice it to say, the lights were turned out on the majority of the work Aluminum Coil Anodizing Corporation performed for several decades.
Biological contamination in tank-line processes can affect part quality, cycle time, auxiliary equipment corrosion, and worker safety.
Because of its face center cubic (fcc) structure, aluminum readily mixes with other metals in the liquid state; however, the solid solubility of various metals is limited to a few percent.
The question sometimes arises of whether the sulfuric acid anodizing bath is made up of volume or by the weight of sulfuric acid.
Fabrication of aerospace structures requires rigorous standards due to the high cost of rework and the severe consequences of in-flight failure.
Adtec II and Veterans Metal have announced a strategic alliance aimed at increasing production opportunities for manufacturing companies.
The metallurgy of 7000 series aluminum alloys is presented as it relates to the base metal surface, the interface from which the anodic aluminum oxide (AAO) grows.
