Give the relative tenacity of the above metals. Lead 1 or lowest.
Tin 11-3 times that of lead.
Zinc 2 times that of lead.
Copper 18 times that of lead.
Iron 271/2 times that of lead.
Give the relative malleability of the five metals.
Copper, tin, lead, zinc and iron?
What does tenacity denote?
The relative power of resistance the metals have, to being torn apart.
On what does the malleability of a metal depend?
A great deal on its tenacity, coupled with softness.
What is the melting point of iron and some of its properties?
Melts at 2786° F., is very ductile and malleable and appears in three forms, malleable, or wrought, in its purest state, or cast, when containing carbon in different proportions.
At what temperature will zinc melt and what are its peculiarities?
Melts at 773° F., is somewhat brittle and fairly permanent in air. It is a protecting coating for iron under the name of galvanized iron, and dissolves easily in acids.

What are the peculiarities of tin and its melting point?

Melts at 428°, is a brilliant white metal in the pure state and produces a peculiar crackling noise when bent, called the "cry" of tin. It is very malleable, but also slightly ductile.

What is copper, its melting point and some of its uses?

An elementary metallic substance of a pale, red color, moderately hard, malleable and ductile. Copper fuses at 1742° F. It is the most useful of all the metals for alloy. Mixed with tin it forms bronze; with zinc it forms brass; is a good conductor of heat and electricity and one of the most useful of metals.
What is brass, its uses and melting point?

It is composed of copper and zinc of different proportions and has no certain temperature for fusing, as the component parts vary; about 1100° F. It is one of the most useful of alloys, more fusible than copper and not so apt to tarnish. It is malleable when cold, but not so when heated.

Describe the properties of lead, its melting point and some of its uses?

Lead is of a bluish gray color, very soft and of slight tenacity. Its proper name is galena or sulphide of lead. It melts at 612° to 617° F., according to its purity. It is used in the arts and sciences, and combines with other metals in various alloys.
