Cast Iron Mechanical Properties

Cast iron has a lot of very good mechanical properties. According to my personal knowledge in Dandong Foundry in China, herein I listed some main chemical properties for the reference to purchasers.

1. Tensile strength

Tensile strength is the most crucial physical property for iron castings. Its unit is RmN/mm2. Tensile strength will show the strength of cast iron when it is pulled until broken. For instance, the ductile iron 60-40-18 has tensile strength of 60000 psi therefore, it is equal to 414 Mpa. As a result, if your parts require to use this material, then your supplier must keep their iron castings with min. 414 Mpa tensile strength.

2. Yield strength

Yield strength is an additional definition to define the strength of cast iron I do not speak about its actual which means here. It is not really required to verify this house considering that it just more deeply measure the strength of cast iron. The tensile strength has currently covered the most of needs to the strength. As for the ductile iron 60-40-18, its yield strength is 40000 psi, equal to about 276 Mpa.

three. Elongation

Often, elongation is quite crucial. High elongation implies the iron casting can be pulled to longer, which implies they have better ductility or called as malleability. For that reason, they will not be broken simply. The ductile iron has higher elongation than gray iron. As for the ductile iron 60-40-18, it has 18% elongation.

four. Hardness

Hardness is also crucial occasionally. As for the machined components, the hardness ought to not be also high to have an effect on the machining method. As usual, the Brinell hardness from 160-220 need to be a great range. Too higher may cause the challenging spots during machining, also low will impact the application. Some purchasers necessary the Rockwell hardness as the normal. As for the comparison among these two requirements, please check our blog.

Some purchasers will demand V Charpy Influence Test to get the influence home of cast iron. This test requirements the professional lab. to perform. As I know, most of iron foundries in China do not have this testing equipment.

Truck hardware parts contain engines, bearing bracket, brake drums, axle supports, gear boxes, radiators. The components of truck hardware components include grey iron, ductile iron, cast steel, and aluminum alloy.

Engines

The engine is to provide energy for automobile. It is an power conversion device. The engine is a device that converts power will chemical energy transformed into mechanical power. The materials of engines include of cast iron and cast aluminum. The cast iron engines extremely powerful and it has far better vibration resistance and wear resistance so its life time is extended. Furthermore, cast iron engines are less expensive than cast aluminum.

Bearing brackets

Bearing bracket is utilised to fix and supports the rotary axes. Bearing bracket need to be have greater vibration resistance, put on resistance and coefficient of heat transfer. So they are normally created by grey iron and ductile iron.

Gear boxes

The material of gear box is generally grey iron. Due to the fact the grey cast iron has very good machinability, excellent wear resistance and vibration damping. In addition, grey cast iron is less expensive.

Brake drums

Brake drum is a element of brake system. It is extensively utilized for the many kinds of vehicles. The material of brake drums is usually grey iron.

Axle supports

The type of axle support consists of front axle assistance, and rear axle support. The material of axle assistance contains grey iron, ductile iron or cast steel.

Radiators

Radiator is to stop the engine temperature is also high, and cooling the engine. The components of radiators contain cast iron, cast aluminum, cast copper. Cast iron radiators are have very good corrosion resistance and it is more affordable. But it is heavy and shape is rude. Cast aluminum radiators are light, but corrosion resistance is poor. Cast copper radiators are have very best corrosion resistance and thermal conductivity, but it is very costly.

Turn Your Back on Me

So I’m guilty of extreme passion in chasing a vision.

A vision that I have no idea what it looks like.

A vision I know that I will recognize when I see it.

And I am not going to make any apologies for that.

It really is a component of me.

I will by no means let you or anyone else crush that.

Because I’d only be letting my soul get crushed.

There can be no compromise.
