Question

Which of the following alloy is used for making scientific instruments?
(A)Steel
(B)Bronze
(C)Brass
(D)Iron

Answer 1

Hint : To answer this question we should have the knowledge of every alloy which includes their properties like magnetic properties etc. Very few alloys are used to make scientific instruments as the scientific instruments need to be errorless so the alloy should be of best quality and be precise in its functioning.

Complete Step By Step Answer:
Brass is an alloy which is used to make scientific instruments because it has higher malleability than other alloys such as bronze or zinc. It is a relatively easy material to cast as it has relatively low melting point and good flow characteristics. Melting point of brass always depends upon its composition. We also know that brass is an alloy of copper and zinc. They are present in mannered proportions but can be varied to achieve electrical and mechanical properties. Brass contains small proportions of many other elements such as arsenic, lead, phosphorus, aluminum, manganese, and silicon. Brass has a bright-gold like appearance.

Note :
Its use is widely found in making utensils due to its many properties such as, low melting point, durability, electrical and thermal conductivity. It is also used in making locks, hinges, gears, bearings, zippers, ammunition, plumbing, hose couplings, valves, and electrical plugs and sockets. It is also used in making musical instruments such as horns and bells. It is also used as a substitute for copper in making costume jewelry and fashion jewelry.
