1. What is Aluminium-Rhenium (Al-Re)?

Aluminium-Rhenium (Al-Re) is an alloy resulting from the combination of Aluminium (Al) and Rhenium (Re), offering unique properties and advantages. This alloy is relatively uncommon due to Rhenium's rarity and high cost. Despite this, the alloy is highly sought after for specific applications due to its advanced material properties, combining the lightweight characteristics of Aluminium and the high melting point and strength of Rhenium.

2. Types of Aluminium-Rhenium (Al-Re) Alloys

Aluminium-Rhenium alloys can be classified based on their Rhenium content in the alloy:

• Low Rhenium Alloys (<5% Re): Enhances strength characteristics without significantly affecting weight.

• Medium Rhenium Alloys (5-15% Re): Offers a balance between strength, corrosion resistance, and high melting point properties.

• High Rhenium Alloys (>15% Re): Provides excellent strength and resistance to high temperatures and corrosion.
