Question

write down the composition of brass, alnico, nichrome​

Answer 1

Answer:

Brass is an alloy of copper and zinc.Alnico is an alloy made mainly from a combination of Aluminium, Nickel, Cobalt and Iron plus varying levels of Copper, Titanium and Niobium. A common nichrome alloy is 80% nickel and 20% chromium, by mass, but there are many other combinations of metals for various applications.

Answer 2

Answer:

Alnico is a family of iron alloys which in addition to iron are composed primarily of aluminium (Al), nickel (Ni) and cobalt (Co), hence acronym al-ni-co. ... The composition of alnico alloys is typically 8–12% Al, 15–26% Ni, 5–24% Co, up to 6% Cu, up to 1% Ti, and the balance is Fe.

Brass is an alloy of copper and zinc, in proportions which can be varied to achieve varying mechanical and electrical properties. ... The composition of brass, generally 66 percent copper and 34 percent zinc, makes it a favorable substitute for copper based jewelry as it exhibits greater resistance to corrosion.

Alnico is an alloy made mainly from a combination of Aluminium, Nickel, Cobalt and Iron plus varying levels of Copper, Titanium and Niobium. The exact chemical composition within Alnico grade depends on the grade of Alnico.

Nickel (Ni): 13% – 26%

Cobalt (Co): 0% - 42%

Copper (Cu): 2% - 6%
