1. What is aluminum-based master alloy

Aluminum master alloy is a traditional product mainly used to adjust the composition of aluminum melt. It is a metal element with a higher melting temperature. The melting method and aluminum are used to produce intermediates. The melting temperature of this intermediate is significantly reduced, thereby causing some The metal elements with higher melting temperature are added to the aluminum liquid at a lower temperature to adjust the element content of the aluminum melt.

Second, the characteristics of aluminum-based master alloys

1. Uniform composition and low melting temperature.

2. Easy to break and easy to join.

3. High content of ingredients, easy to absorb.

3. Usage and dosage of aluminum-based master alloy

1. According to the required control standard of the elements in the melt and the standard content of the master alloy, calculate the amount of master alloy required to prepare the total amount of the melt

2. Generally used to adjust the composition, add the master alloy charge together and spread it evenly in the middle of the charge.

3. After the melt is melted, stir it evenly and sample for analysis.

Four, packaging and storage

1. All alloy ingots are supplied according to national standard ingots, each of which is a bundle of four ingots, with a net weight of about 25 kg.

2. The front of the alloy ingot has the alloy code and the production date and heat number.

3. Store in a dry warehouse.

4. Take a sample for laboratory test, take any one piece, take three points from the upper surface (smooth surface) of the alloy ingot along the diagonal aluminum and mix it for processing and analysis.
