Aluminum strontium alloy

Release Time:1/15/2019 12:00:00 AM

  Aluminum strontium alloy:

  1. Purpose: used in aluminum alloy casting, alloy preparation and other industries.Refine and optimize the microstructure of al - si alloy.

  2. Shape:

  Pie shape: 0.25 kg/piece.

  Waffle: 7 ~ 8 kg/piece.

  Rod diameter: 9.5 mm, length 0.5 m or 1 m.

  Appearance: rich metallic luster.

  3. Ingredients:

  Sr: 9 ~ 11%.

  4. Methods:

  The reference amount is 0.2 ~ 0.6% of the aluminum (new material) to be processed.

  The residual strontium in aluminum solution (strontium in the furnace charge) is still effective and will have different degrees of metamorphism on different alloys.The amount to be added in this case depends on the site or the test.

  Metamorphic treatment is generally carried out after refining, before baking and drying.Aluminum liquid temperature 720 ℃ ~ 760 ℃, to join in furnace inoculant, stir well after melting.After 10 to 20 minutes of static setting, the dregs can be removed and the test bar can be poured when the fracture inspection is normal.Secondary refining can be carried out according to the requirements after metamorphic treatment.

  The effective time of metamorphism: 4 ~ 8 hours.

  5. Description: this product is non-toxic, harmless and non-corrosive.

  Preservation: keep dry and anticorrosive.
