Saru Modifier Al-Sr-10 (Tablet/Cut length):
Product: Saru Modifier-Sr 10% is modifier for Al-Si for eutectic aluminum alloys. They are particularly suited for all alloy properties, gravity die castings such as cylinder heads, manifolds, aluminium alloy wheels etc., The purpose of modifying eutectic Al-Si alloy is to change the acicular form of silicon to a spherical or globular form. The modification treatment improves the mechanical properties in both the as cast and heat-treated condition.
Advantages:
Al-Sr modifier has following advantages:
- Improves mechanical properties
- Increases resistance to fatigue
- Improves casting machinability
- Reduces hot tears
- Increase feeding rate of aluminum melt
- Reduce cracking in rolled & forged products
Application
Prepare the desired alloy composition. Follow the normal fluxing and cleansing procedure recommended for using suitable flux from Saru flux range. Degas the melt with a suitable grade of D’GASSER and dross off. After degassing operation, add Saru Sr-10 modifier depending on the melt size and rabble it to ensure homogeneity of the composition. Wait for minimum 10 minutes for modification effect to take place. Take a sample for checking the modification effect, if satisfactory start the cast.
Application Rate:
Packing:
- Available in 200 gm tablets form, cut length, cast cut rod etc,
Precaution:
Degassing and fluxing using chlorine-based products must be avoided after modification using Saru-Sr-10; otherwise, it results in strontium loss in the melt.
