Micro
Expanded Metal is a specialized type of expanded metal characterized by its very small openings and fine thickness. This material is produced through a precise expansion and stretching process, which allows it to maintain a high level of strength while being significantly lighter than traditional solid metal sheets. Here’s a detailed overview of micro expanded metal, including its properties, applications, and benefits.
Key Characteristics
- Lightweight: Micro expanded metal is considerably lighter than solid metal sheets of the same size, making it ideal for applications where weight reduction is critical, such as in aerospace and automotive industries.
- High Strength: Despite its lightweight nature, micro expanded metal offers enhanced structural integrity, allowing it to withstand greater pressures and loads.
- Versatile Materials: It can be manufactured from various materials including mild steel, aluminum, stainless steel, copper, nickel, and titanium, providing options for different environmental conditions and requirements.
- Excellent Conductivity: The material exhibits high conductivity and is effective in applications requiring electromagnetic shielding or heat transfer.
Common Applications
Micro expanded metal is utilized across various industries due to its unique properties:
- Aerospace: Used in the manufacturing of satellites and spacecraft, micro expanded metal helps shield sensitive equipment from electromagnetic interference and radiation.
