Produce low cost precious metal clad with copper alloys or the other base metals by plating, rolling and annealing process.

Copper Alloy Clad Metal Sheet With Precious Metals

 

  Features(Overview)                                                                                               

 

JLC - low cost clad metal is a more adhesive metal than a normal electroplating metal.,

is cold-rolled and heat treated after the base metal has been plated. JLC offers the following benefits.

 

• Rolling and heat treatment eliminate pinholes in the plating,

  and promote deffusion bonding of boundary lines.

 

• Compared to treatment with plating only, JLC has abrasion resistance,

   good workability and adhesion.

 

• JLC made it possible to produce thinner thickness clad,

   enables cost savings through the use of precious metals in this manufacturing process.

 

  Main uses                                                                                                              

 

Connectors, contacts, terminals, pin switches and so on.

The best for electrical components which need high conductivity, durability, and abrasion resistance.

Especially suitable for improving conductivity of contact points by using precious metals (silver, gold).

Manufacturing Processes	Outline
Base metal	We carefully balance quality, delivery time and price, procure various base matals from all over the world. We manufacture appropriate products to your needs.
Cold rolling	We have rolling machines like 18-high mills (Z-High type), 24-high mills (Sendzimir type), and 4-high mills, etc. We choose suitable rolling machine for each specification of metals. An AGC program in rolling machines controls pressure and position, enables an accuracy of ±1~3μm at thicknesses 0.20 mm or less, and ±1% at thickness greater than 0.30 mm in cold rolling process.
Plating	Although electroplating is subcontract processing, we can choose the proper company from our multiple partners to meet your demand.
Annealing	We possess BA (Bright Annealing; Continuous-Type ), BELL(Bell-Type), and TA (Tension Annealing; Continuous-Type ) furnaces. Annealing for internal stress removal is also possible as well as soft annealing. Moreover, according to our accumulated experience and know-how, we can control the size of metallographic structure (carbide grain size).   Annealing process after plating of JLC (Low cost clad metal) make plating metal and base metal bond strongly by diffusion bonding structure at the interface between two materials.
Surface inspection (CCD)	All-digital processing by CCD camera detect surface defects. This high precise inspection machine detects even the minute scratches on a flat surface.
Slitting	Saitama plant has 7 different type of slitting machines, so we use the appropriate machinery for your metals and specifications. We can guarantee high quality slitting, like width tolerance and burr by setting optimum conditions for each metal's specification.
Sample inspection	We have furnished all the measuring equipments for mesuring metal properties and specifications, such as hardness and tension, etc. We also possess SEM (Scanning Electron Microscopes ) with EDX function. Furthermore, we have FE-SEM (+EBSD+EDS) which is more precise than SEM, so we can analyze micro crystal structure, too.
Packing	In order to prevent damage, rust, or other flaws arising in our products under transit, we alter our package one by one. We also accept specific packaging requests from you.
