Gas checks are most commonly found in the form of a thin cup or disc made of a ductile metal. Copper, zinc, aluminum, and alloys such as brass have been used. A bullet designed to accept a gas check has a rebated base shank which permits attachment of the check without altering the maximum diameter of the bullet.
The Dyna-Cam engine originally came from a design by the Blazer brothers, two American engineers in the brass era automotive industry who worked for Studebaker in 1916. They sold the rights to Karl Herrmann, Studebaker's head of engineering, who developed the concept over many years, eventually taking out US patent 2237989 in 1941. [ 15 ]
Aluminum sacrificial anodes (light colored rectangular bars) mounted on a steel jacket structure. Zinc sacrificial anode (rounded object) screwed to the underside of the hull of a small boat. Cathodic protection ( CP ; / k æ ˈ θ ɒ d ɪ k / ⓘ ) is a technique used to control the corrosion of a metal surface by making it the cathode of an ...
But the Ansonia Brass and Battery Company joined the new firm in their place. [2] American Brass began operation on December 14, 1899. [1] [2] There were about 10,000 brass workers in the United States in 1900, and half of them worked for American Brass. [3] Benedict & Burnham and Holmes, Booth and Haydens became part of American Brass in 1901. [2]

Aluminium bronzes are most valued for their higher strength and corrosion resistance as compared to other bronze alloys. These alloys are tarnish-resistant and show low rates of corrosion in atmospheric conditions, low oxidation rates at high temperatures, and low reactivity with sulfurous compounds and other exhaust products of combustion.
Dealuminification is a corresponding process for aluminum alloys. Similar effects for different metals are decarburization (removal of carbon from the surface of alloy), decobaltification, denickelification, etc. The prototypical system for dealloying to create nano-porous metals is the np-Au system, which is created by selectively leaching Ag ...
Two transfer cases were offered: the Dana 20, available only with the manual transmissions, or the NP-205, available with both types of transmissions. The Blazer had 8 inches (200 mm) of ground clearance and an approach angle of 35°. [2] Engines. 250 cu in (4.1 L) High Torque I6 (1969–1984) 292 cu in (4.8 L) High Torque I6 (1970–1971)
