Step-by-Step: 5 Popular Uses & How to Apply

1️⃣ Resin Cold Casting (Decorative Objects)

1. Measure 100 g resin

2. Add 20–40 g aluminium powder

3. Mix thoroughly until uniform

4. Pour into mould and allow to cure
   ⚠️ Wear gloves and a dust mask during mixing

2️⃣ Thermal Conductive Resin Fill

1. Prepare 500 g epoxy resin

2. Add 50–150 g aluminium powder depending on conductivity required

3. Mix slowly to avoid air bubbles

4. Apply to mould or surface

3️⃣ Powder Metallurgy (Lab Scale)

1. Measure 1 kg aluminium powder

2. Compact under controlled pressure

3. Sinter in furnace below 660 °C
   ⚠️ Use inert atmosphere where required

4️⃣ Metallic Coatings & Paints
