What Are Some Of The Designations Used To Denote ZA27?

Designations to denote ZA27 alloys are,

  • AC41A
  • Z35841

Why Is ZA27 Alloy Suitable For Die Casting?

This is because of corrosion resistance, its light weight and its strength at high temperatures.

This makes it one of the best alloys for die casting.

Additionally, this is because of its combination properties for casting both physical and mechanical. It’s good with dimensional stability retention of shapes.

Besides, it offers better thermal and electrical conductivity.

AZ27 alloy is used for intricate components with specific die filling characteristics of high strength at high temperatures hence cracks under heat is minimal.

Due to excellent ductility with high resistivity to corrosion and higher temperature strength, we may consider AZ27 alloy.

How Do I Test ZA27 Hardness?

Below is a procedure how to test ZA27 hardness:

  • Clean the specimen surface
  • Fix an appropriate indenter then place the specimen on the anvil table
  • Check clarity of specimen on the screen then adjust the knob when necessary
  • Bring indenter over the specimen while rotating the index disc.
  • Keep pressing the start button to glow the dwell light.
  • Load the specimen and wait for the load to be removed automatically.
  • Using the projections of image on the screen, measure diagonals of the impression.
  • Using the formula VHN=1.854p/d2 to determine the VHN.

Is ZA27 Corrosion Resistant?

The presence of aluminum in AZ27 alloy enhances the carrion resistance property.

Also, its non-sparking nature when exposed to iron makes it resistant to humid atmosphere.

Again, you should note that the corrosion rate to raw water is very low.

How Would You Describe ZA27 Strength?

It is important to note the following:

  • ZA27 has high tensile strength, perfect for construction and building work.
  • Compressive strength measures how compact or squeezed a material can resist.
  • Impact strength measures how a material can withstand an impact
  • Yield strength measure resistance effect of bending or shaping of a material.

Once you have all these, it will be easier to determine the specific application of ZA27 alloy

How Is ZA27 And Other Zamak Alloys Compare?

When it comes to choosing between ZA27 alloy and Zamak alloy, here is all you should know:

ZA27 AlloysZamak Alloys
In strong alkaline solution, corrosion takes place.The reaction is similar in alkaline solution.
Has high melting pointsLow melting points
It has optimum hardness propertiesHas increased hardness properties, wear resistance and abrasion.
Are non-sparking and work best in explosive environment.When exposed to rusty iron component, they easily generate sparks.
They solidify with tightness in pressure into a dense strong matrix thus poor dimensional stability.Are casted and are long term dimensionally stable.Can be fabricated to small different shapes.

How Does ZA27 Strength Compare To That Of Aluminum?

ZA27 AlloysAluminum Alloys
It is a light weight alloy used in materials that require optimum strength.Because of its good energy absorbing impact, light weight and durability, it is used in construction cars, trucks etc.It is also reliable, used in fighting vehicles for corrosion resistance.
ZA27 withstands load due to its plastic deformation properties.Has good plasticity, very flexible thus can be processed into different shapes.

In short, before choosing any of these alloys for your applications, know the strength of each alloy grade.
