High purity aluminium special products

Aluminium<chemical name>

High-purity aluminum materials with a purity of over 99.99% are used in the electronic components field, such as for sputtering targets and evaporation materials, as well as in the superconductive materials field. In the future, it is expected that more applications that take advantage of the characteristics of high-purity aluminium will be developed. We will introduce these high-purity aluminum products and technologies to many customers, and assist in the research and development of various applications that are expected in the future.
We provide a variety of shapes and high-purity aluminum-based alloys in small lots to meet the needs of our customers.

Purity of High-purity Aluminium, Unit:%

	Si	Fe	Cu	Al
4NAl	≦0.006	≦0.004	≦0.008	≦99.99
4N8Al	≦0.0006	≦0.0004	≦0.0008	≦99.998

We also accept consultations regarding trial production of alloys based on high-purity aluminum.

Characteristics of High-purity Aluminium and its Applications

Excellent electrical conductivity: ⇒Conductive materials, sputtering target materials
Excellent corrosion resistance: ⇒Etching materials, battery materials
Large residual resistance ratio: ⇒Superconductor stabilizing materials
High reflectivity: ⇒Reflector materials
High cutting accuracy: ⇒Ultra-precision cutting materials
Easy to form into a cube: ⇒Foils for medium and high voltage electrolytic capacitors
Difficult to work-harden
