Description

"Physical Properties of Metal Materials" Metal PPT Courseware

Metallic materials refer to pure metals and their alloys collectively referred to as metallic materials.

common physical properties of metals

Most metals are silvery white

Most metals are solid

Most metals are shiny

Most metals conduct electricity and heat

Most metals have high melting and boiling points

Most metals are ductile

Different metals also have their own characteristics

The electrical conductivity, thermal conductivity, density, melting point, hardness and other physical properties of different metals are also quite different. For example

Most metals are silvery-white, but copper is ___________ and gold is ___________.

At room temperature, most metals are solid, but mercury is ___________.

2. Alloy

1. An alloy is a mixture with metallic properties formed by the fusion of one metal with one or several other metals (or non-metals).

2. Differences in properties between alloys and the metals that make them up.

⑴The alloy is brighter in color than its component metals;

⑵Alloys are harder than the metals they are composed of;

⑶The melting points of alloys are lower than the metals that make them up;

⑷The corrosion resistance of alloys is generally stronger than that of the component metals.

3. Alloys have wider uses than pure metals.

4. Titanium and titanium alloys, new metal materials

practise

1. What properties of iron are involved in the following uses of iron?

(1) The shovel used for cooking is made of iron and usually has a wooden handle.

Iron has good thermal conductivity

(2) Iron blocks can be made into iron wires or iron sheets

Iron is malleable

(3) When the tank truck is driving, the oil in the tank oscillates to generate static electricity, which is prone to fire hazards. Therefore, there is an iron chain mopping the ground at the rear of the tank truck.

Iron is conductive

2. Among the five metals: iron, aluminum, copper, zinc and titanium:

The metal commonly used for electroplating and dry battery electrodes is_

Which metal are alloys of pig iron and steel?

Silver-white metal material for packaging candies and cigarettes＿＿

Metals commonly used in making wires and cables ＿＿

Metal commonly used in the aviation industry to make aircraft and other materials __________
