LEX Series: Low Thermal Expansion Materials for Extremely Low to High Temperatures

A wide range of products from ultra-low temperatures to high temperatures! New materials that cover thermal expansion characteristics.

In various advanced fields ranging from optical devices and electrical components to ultra-precision machine tools and semiconductor-related device parts, overcoming thermal displacement of the materials used, which is a factor in precision errors, has become a bottleneck for achieving high precision. At Nippon Casting, we focused on the thermal expansion characteristics of inverter-type alloys and successfully developed the 'LEX series' by balancing the conflicting properties of low thermal expansion with castability and machinability through unique chemical compositions and advanced heat treatment. In response to diversified precision requirements, we offer a wide range of materials that cover a broad spectrum of thermal expansion characteristics. This has earned us high acclaim not only in the ultra-precision equipment sector but also in various fields, including CFRP (carbon fiber reinforced plastic) molds primarily for aircraft, vacuum pump parts, and laser equipment components. 【Main Products】 ■ Flat plates for ultra-precision grinding machines ■ CFRP molds for semiconductor manufacturing equipment ■ Frames for laser measuring instruments ■ XY stages *For more details, please refer to our catalog or feel free to contact us.

Low thermal expansion material LEX-SF1 processed product cut by band saw.

Since it’s a made-to-order product, you might think that a delivery time of about one month is standard... But did you know that as a steel supplier, we have stock on hand? Depending on the size, we can offer immediate delivery!

Our company realizes short delivery times even for small lots of various types of steel materials due to the wide variety of products we handle and our abundant inventory. We accept orders starting from just one piece, including bending, drilling, milling, laser cutting, gas cutting, water jet cutting, and BTA processing. 【Processing Example】 Material: LEX-SF1 (low thermal expansion alloy) Size: t12 (6+6) × 150 × 268 Processing Method: Cut out using a band saw Application: For parts that require precision. For areas that should not be affected by heat. 【Benefits of Processing at Our Company】 ▼ Typically, manufacturers take about a month for made-to-order production, but since we maintain inventory of blocks of a certain size, we can offer immediate delivery within the range of applicable sizes! *For procurement of metal processed products, contact "Ito Akira Sangyo"!

Super Invar Processing Example (INVAR SUPERINVAR)

Sizes and shapes can be accommodated up to approximately Φ150.

Super Invar is a material known for its extremely low thermal expansion. Due to its hardness and low thermal conductivity, it is classified as a difficult-to-machine material. It is used in areas of products that are sensitive to temperature variations, and most of it is required to be precisely machined for the product's core section. It can accommodate various sizes and shapes up to approximately Φ150. 【Specifications】 ○ Material: Iron ○ Lot: --- ○ Precision: --- For more details, please contact us.
