High Compressive Strength Tungsten Carbide Concave Mold and Convex
Mold
Tungsten carbide concave mold and convex mold, are the commonly
used core working parts such as continuous stamping mold, custom
progressive mold components.
Case-hardened and precision-ground is to meet the requirements of
metal or non-metallic material cutting, pressing, cutting, forming
and other industrial processing.
The size tolerance is ±0.005, the verticality, flatness and
parallelism are 0.002.
High hardness, high strength of tungsten steel material after
precision processing with mirror finish, is a hard metal material
of good performance for tensile concave mold insert.
Good wear resistance last long for mechanized automatic production
line. High wear resistance is the basic requirement of tungsten
carbide mold, especially for the core work of precision equipment.
Above all, as an industrial tooth, tungsten carbide product with
its high hardness, high strength and high wear resistance
performance, is born for the mass industrial production.
The physical performance parameters of tungsten carbide concave
mold insert are as follows:
| 1 | Grain size (um): | 1.0 ~ 2.0 |
| 2 | Cobalt content (Co%): | 8.0 ~ 10 |
| 3 | Density (g / cm³): | 14.41- ~ 14.95 |
| 4 | Hardness (HRA): | 89.5 ~ 93 |
| 5 | Bending strength (Mpa): | 3200 ~ 4500 |
| 6 | Young's modulus (Gpa): | 570 ~ 620 |
| 7 | Compressive strength (Mpa): | 4700 |
Advantages:
Our company can customize all kinds of hard alloy (tungsten steel)
non-standard shaped parts according to the drawings or samples
provided.
The concept of cemented carbide: A composite material consisting of
refractory metal compound (hard phase) and binder metal (bonded
phase) produced by powder metallurgy.
Basic characteristics of cemented carbide:
1. High hardness and high wear resistance
2. High modulus of elasticity
3. High compressive strength
4. Good chemical stability (acid and alkali resistance, high
temperature oxidation)
5. Low impact toughness
6. Low expansion coefficient, thermal conductivity, electrical
conductivity and similar to iron and its alloys
Application of cemented carbide: modern tool materials, wear
resistant materials, high temperature and corrosion resistant
materials.
Applications:
The Astonishing Applications of Tungsten Carbide
Tungsten carbide is a material widely used in many settings due to
its incredible hardness and durability. Its many uses span across a
variety of settings, such as cutting tools, wear parts, dies and
molds, orthopedic implants, drill bits, wind turbine components,
exploration equipment, abrasives, and even the jewelry industry.
Cutting Tools
Tungsten carbide is used to create hardened tips and cutting edges
for several drills, end mills, taps, reamers, and other types of
tooling used to perform material-removing processes.
Wear Parts
Items like bulldozer blades, excavator teeth, conveyor skip plates,
and chute liners require excellent wear-resistance and tungsten
carbide provides just that.
Dies and Molds
Forming and stamping dies used in shaping metals and plastics
require a material that can withstand repeated use and high
pressure. Tungsten carbide fits these criteria.
Orthopedic Implants
Biocompatibility and mechanical strength are just two of the main
requirements that tungsten carbide meets when used in joint
replacement components, like knee and hip prosthetics.
