tk Ultra 7 Mold Plate® is a high-strength 7000-series aluminum alloy designed for use in various mold-making applications such as injection molds or blow molds. tk Ultra 7 Mold Plate® has high thermal conductivity, high strength, consistent hardness throughout the thickness, and greater corrosion resistance than typical 7000-series aluminum alloys. Due to its chemistry and the heat treat practice, tk Ultra 7 Mold Plate® is a better choice over other high-strength alloys for resisting exfoliation corrosion and stress corrosion cracking. Additionally, tk Ultra 7 Mold Plate® can be polished to a very fine finish (SPI A2) and is available in standard thicknesses of 1.000” to 20.000” from stock.

Benefits of tk Ultra 7 Mold Plate® over P20 Steel are:

• 1/3 the weight of steel, which reduces wear on molding equipment
• Machines 8-10 times faster, resulting in lower mold costs and shorter mold-build lead times
• Excellent thermal conductivity, resulting in 20% - 40% improved cycle times
• Better corrosion resistance over other high-strength aluminum alloy

Characteristics

Very high strength, good exfoliation corrosion resistance

Typical Uses

Blow molds and injection molds.
