Advantage And Disadvantage Of Forging

ALUMINIUM FORGING

 Why is Aluminum Forged

The recent widspread of light weight metals in the transport sector has replaced steel made materials .Aluminum has a wide range of applications and it is most widels used these days because of its light weight and strength It is clear that some of the emerging casting technologies deserve close examination when considering fabrication options available to the designer, however the characteristics of a relatively simple forged design often provide the desired weight + strength at low cost. These characteristics are clearly understood by some Australian automotive suppliers .

 Strength

When forged and heat treated the aluminum exhibits many properties as compared to high grade steals .The strength

Forging results in metallurgical recrystalisation and grain refinement as a result of the thermal cycle and deformation process. This strengthens the resulting steel product particularly in terms of impact and shear strength.Forged steel is generally stronger and more reliable than castings and plate steel due to the fact that the grain flows of the steel are altered, conforming to the shape of the part.

 Advantages of forging

 Generally tougher than alternatives

 Will handle impact better than castings

 The nature of forging excludes the occurence of porosity, shrinkage, cavities and cold pour issues.

 The tight grain structure of forgings making it mechanically strong. There is less need for expensive alloys to attain high strength components.

 The tight grain structure offers great wear resistance without the need to make products “superhard” We have found that, on a blank HRC 38-42 forged grinder insert wear/wash is about the same as a high alloy HRC 46-50 cast grinder insert. The difference being a HRC 46-50 casting does not have the ductility to handle high impact grinding.

LOST FOAM

If a die is used to create the patterns there is a large initial cost

Steps For Making the Aluminium Forge

• First collect all the parts require for making the aluminium forge

• The material that were used for the making of the forge were

• A steel bucket made up of hard steel so that it may be able to bear the temperature for the forging process

• A propane torch which will be used as the fuel for the forging if propane torch is not available we may use the charcoal but propane torch is mostly preffered over charcoal.

• A hacksaw which is used for cutting

• A drill machine used for drilling the hole in the steel bucket for the propane torch to be inserted the bucket

• A small steel hard can which will be used as putting the aluminium pieces to be melted

• A ball peen hammer

• Safety
