Anviloy for Die Casting

Anviloy metals containing tungsten and molybdenum are well-recognized to solve the problems with molds (insufficient thermal conductivity, high wear, sticking of aluminum) in die casting. The most commonly used hi-tech tungsten materials in the die casting industry are Anviloy1150, Anviloy1350 and Anviloy weld rod. Using Anviloy tungsten alloys during the foundry process can both improve quality and lower costs.

Anviloy series is material specified by North American Die Casting Association (NADCA).

Anviloy vs. Tool Steel 1.2343

1. 4 times higher thermal conductivity.
2. 5 times better heat crack resistant.
3. 2 times lower soldering tendency.

Features and Benefits of Anviloy

1. High resistance against dilution Reduces corrosion and erosion.
2. High hardness and strength at high temperature can increase stability of form and dimensions.
3. Superior thermal conductivity and tempering resistance help remove heat quickly and reduce soldering and heat cracks
4. Easy to machine and can be machined to any forms you need.

Main Products

1. Core pins and inserts.
Anviloy® core pins are widely used to remove heat fast, increase the service time and reduce sticking of aluminum to the pins.
Inserts are mostly used to reduce wear of certain mold areas and remove the heat faster to improve cast quality and decrease cycle times.
2. Spreaders
Anviloy® spreaders are used in areas where liquid aluminum is pouring into the mold and spreads by this cone to distribute it in the mold. It is often used in wheel die casting. Service time is multiple times higher compared to tool steel.
3. Anviloy® mold enhancement products
The benefits of Anviloy® mold enhancement products
(1) Reduced corrosion and erosion
(2) Increased form stability
(3) Improved stability of dimensions
(4) Fast removal of heat
(5) Minimized heat check
(6) Reduced soldering
(7) Minimized release angles
