3

INTRODUCTION

What is an alloy?• Alloys are mixed of metal with other metal or non-metal in the

same group that are prepared by mixing of the metals in their molten state through physical processes.

4

INTRODUCTION

Preparation of alloys

• Alloys can be made by combining two or more metal elements while in a molten state or by bonding metal powders.• Made through physical processes. • Determining physical and chemical properties.

5

WHY ALLOYS?

The aim of making alloys:• To increase the hardness and strength of a metal.• To prevent corrosion or rusting.• To improve the appearance of metal surface.

6

IMPORTANCE AND USES OF ALLOYS

• Military, aircrafts, commercial, industrial, and manufacturing applications.• Industrial of making coins, turbines , pipes and blades.• Jewelry, and uses in structural materials• In automobile industrial.

7

TYPES OF ALLOYS

• Cast alloys • Bearing alloys• Corrosion-resisting Alloys• Super-Austenitic Stainless Steels Alloy (SASS Alloy)• High-Strength Corrosion-Resistant Alloys

8

PROPERTIES OF ALLOYS

• Strength

• Conduct electricity

• Durability

• Resistance of corrosion

• Ability to withstand heat
