Do you really know the difference between SIC and ALO ballistic inserts?

DATE: Oct 20th, 2023
When talking about SIC and ALO ballistic inserts, they differ sharply in a number of key aspects, which include basic characteristics, ballistic performance, longevity, price and application areas. Here's how they compare on these dimensions:

Basic Characteristics:

SIC (Silicon Carbide): extremely durable with high hardness and strength.
ALO (Aluminum Oxide): Excellent heat and corrosion resistance.

Bulletproof properties:

SIC: SIC usually has better anti-elasticity performance, and can effectively absorb energy from ballistic impacts and mitigate impact damage.
ALO: ALO also has good ballistic performance, but its energy absorption capacity may be slightly lower than SIC.


SIC: SIC inserts typically have a longer lifespan and are less prone to wear or breakage.
ALO: ALO may require more frequent maintenance to ensure performance, so its lifespan may be relatively short.


SIC: In general, SICs are more expensive to manufacture and therefore are usually more expensive.
ALO: ALO is usually more economical and less costly.

Application Areas:

SIC: Due to its excellent resistance to elasticity and durability, SIC is mainly used in military and defense applications, such as bulletproof vehicles and protective equipment.
ALO: ALO is suitable for a number of civilian applications, especially industrial applications requiring high temperature environments, such as high temperature kilns or smelting furnaces.

In summary, there are clear differences between SIC and ALO, with each material having its own specific advantages and disadvantages. The choice of material depends on the specific needs, budget and level of performance required. Whether you are looking for a highly ballistic material for a military application or an industrial application that requires use in high temperature environments, understanding these differences is critical to making the right choice.
