oswald extensively tested various duralumin-built components with the intent of using duralumin for aircraft construction. many wondered whether or not duralumin would resist corrosion. to prove the metal was up to the task, oswald affixed duralumin and mild-steel plates to a jetty so that they were exposed at low tide and submerged in the sea at high tide.

it can be spun into ropes or sheets of fabric that can either be used as-is, or used in the construction of composite components. it is now used in a wide range of applications - from bicycles to bulletproof jackets - due to its high strength-to-weight ratio, five times greater than that of steel.

h. oswald short and his brother eustace founded short brothers in london, england in 1908. in 1916, they became acquainted with duralumin when their firm took over construction of two airships that used duralumin components. duralumin is an aluminum alloy that incorporates copper, manganese, and magnesium for increased hardness.

pumps constructed of steel are used for zinc alloys and magnesium alloys. there are still some problems with the durability of ceramic pumps needed for aluminum alloys. in a variant of the process, direct injection of zn alloys takes place through a heated manifold and mininozzles, so that gates and runners are eliminated and the yield is raised. 2 the cold-chamber process uses separate melting facilities.
