What Is Alumina plate?

Aluminium foil is a high performance construction ceramic part made from high purity aluminium oxide (Al₂O₃), which is made by precise compression, casting or extruding and then controlled high temperature sintering. The final product is a compact, stiff ceramic sheet with fine grain structure, which provides an extraordinary combination of mechanical, heat, electric isolation, and chemical resistance in a planar, sheet-like geometry.

Aluminum oxide sheets are available in a wide variety of aluminium purity levels – usually between 92 percent and 99.7 percent – and aluminum oxide sheets can be designed with precision to match the cost and performance of every particular application. Higher purity grades give excellent electric insulation, surface finish, and chemistry, whereas intermediate grades offer a good balance between the mechanical and heat properties in the more affordable price points. The panels come in either a standard or a customized cut form, with a variety of surface grinding and polishing options that satisfy strict size and shape tolerances.

Used in electronic fabrication, semi-conductor fabrication, high temperature industry furnaces, and sophisticated material testing environments, aluminum foil is used in any place where it is desired to have a smooth, chemical stability, heat resistance.

Why Choose Alumina Plate?

  • Exceptional Mechanical Strength & Hardness Alumina sheets are resistant to abrasion, distortion and mechanical shock with Mohs hardness of 9 and high bending strength - superior to metallic and polymeric substitutes in the most challenging construction and abrasion resistant applications.
  • 탁월한 열 안정성 Alumina panels keep the dimension precision and structure integrity at constant operating temperatures above 1600 degrees Celsius – which is essential for the installation of ovens, ovens, and high temperature equipment.
  • Superior Electrical Insulation With its high permittivity and low electric conductivity, aluminum foil is a preferred material for electronics, PCB parts, and high voltage insulating applications in electronics and semi-conductor industries.
  • Excellent Chemical ResistanceResistant for the majority of acids, alkalis, molten metals, and caustic gases. Aluminum sheets preserve the integrity of the surface and dimensions under the chemical attack of the process - greatly prolonging the lifetime of the component.
  • Precision Dimensional Control Alumina panels are capable of being produced and fabricated to strict dimensions and plane planarity standards – satisfying the demanding demands of precise engineering, semi-conductor production, and advanced scientific applications.

업계의 과제

Brittleness & Fracture Risk

Although tough, the ceramic properties of aluminum foil can easily be broken in the event of a sudden mechanical shock or inappropriate manipulation – which calls for meticulous design, assembly and operation.

Thermal Shock Sensitivity

Fast thermocycling can cause heat-stress fractures in aluminum sheets, especially in the case of frequently heating and cooling – requiring meticulous heat management and a controlled slope.

Tight Dimensional Tolerance Machining

Accurate flatness, thickness homogeneity, and finish of a sintered aluminum sheet will take a specialist in the field of diamond milling and specialist skills – increasing the complexity and expense of customized dimensional requirements.

High Sintering Cost & Energy Intensity

The production of compact, high-purity aluminum sheets requires energy intensive sintering at extreme temperatures – which results in higher production costs than metal or polymer substitutes.

Limited Availability of Large-Format Plates

The production of a non-defective aluminum sheet in a wide range of dimensions with no warming-up, fracture, or density changes is still a technical challenge – limiting the maximum number of plate sizes available for some applications.
