Sanzen Seiko - Stepped into forging business

(Source: The Nikkei, December 20, 2017)

Sanzen Seiko Co.,Ltd, metal processor (Shiojiri-shi), launches forging business to enhance strength of Aluminum alloy by means of compressing.  New facility will be constructed in main site with approximately 580 million JPY investment to produce automotive parts from upcoming 2019.  Advantages of forging are to enable higher strength by lower cost.  Mass production will be anticipated eyeing Auto Aluminum parts demand rise replacing steel along with ongoing Automotive weight reduction.

Company also intends to try Magnesium forging, which is lighter than Aluminum.  

Since magnesium alloy breaks easily if being forged at room temperature, new warm forging method using heated tooling was developed jointly with Nagano Prefecture General Industrial Technology Center under Yamanashi University’s advice.

Magnesium alloy received attention as material for various parts such as camera, laptop housing and automotive parts.  Company is going to propose forged parts with showing forged samples to potential users.  Warm forging technology will be applied to Aluminum alloy, which will contribute to complicated shape.

Nissin Industry - Magnesium-containing Zinc powder paint registered to NETIS, MLITT

(Source: Japan Metal Daily, December 25, 2017)

On December 22, Nissin Industry announced that Magnesium-containing Zinc powder paint “MAZAX” was registered on ”NETIS”, New Technology Information System for public construction by Ministry of Land, Infrastructure, Transport and Tourism.  Anti-rust ability is superior than existing Zinc or Zinc-Aluminum type paint and contributes to improve human-work efficiency. Being registered above, it is expected to accelerate sales as repair paint for high-corrosion-resistant paint.

Magnesium powder has been used for raw material of welding wire but there was an issue powder diameter was too large to mix into dry paint film.  However product was successful to make average powder diameter smaller by powdering aluminum and magnesium at ratio 1:1 and combining with Zinc powder.

Furthermore, since it contains zinc, aluminum and magnesium, it shows the same components as high corrosion resistant plating, which leads to become usable as repair agent. It is applicable to various paint method such as aerosol spray, brush coating and airless spray with various paint area volume.

 i-TEQX - Corrects record disc warpage to improve sound quality

i-TEQX Co., Ltd (Yahiko village), Metal products maker, developed equipment which corrects record disc warpage to improve sound quality by mitigating up-and-down motion of stylus, called “Vacuum Disk Mate IQ1300A”.  Subsidiary company “i-qual” (Tsubame-shi) newly released on December 25.  Gramophone record is currently popular, by which company studied and estimated the potential needs at 500 set sales a year.

The equipment is consisted of vacuum pump and magnesium disc which reduces fine vibration during disc play. Just to put this disc on turntable and set up a vacuum pump at the disc center. Record disc will stick to mg-disc by being removed the air between mg-disc and record disc out from center hole. According to company, adsorption enables to correct the disc distortion to flat and to reduce stylus’s up-and-down motion caused by space between record disc and turntable, which leads to improve sound quality. Standard retail price is 75,000 JPY (Tax excluded). Please call 0255-77-8811 for detail information.

The grand total was 3,846.9 tons, 23.1% increase on month-to-month basis (17.4% decrease).

The metal is consisted of 4 categories as follows: 1) 2,734.6 tons of pure magnesium, 30.1% increase on month-to-month basis (21.3% decrease) though import from Turkey stopped again; 2) 666.6 tons of die-casting alloys, 34.8% increase on month-to-month basis (15.7% increase); 3) 1.6 tons of high purity magnesium, 102.4% increase on month-to-month basis, which implies a certain high purity application became fixed stably; 4) 16.6 tons of casting alloy, 6.9% decrease on month-to-month basis (127.3% increase) remained a standstill after favorable growth.

As for the average import price of magnesium metal in November, a upward trend of pure magnesium finally stopped and became 255.2 JPY/kg, 9.4 JPY or 3.5% decrease on month-to-month basis.  For side note, increased about 14 JPY/kg from same month of previous year.  The price of magnesium alloys was 301.9 JPY/kg, 16.3 JPY/kg or 5.1% decrease on month-to-month basis.

As for the total amount of import from January to November 2017, magnesium metal was 30,952.7 tons (11.8% increase from same period of previous year), which surpassed 2016 fiscal year total amount by 677 tons. Magnesium powder was 3,436.0 tons (3.8% decrease) and other products was 2,134.6 tons (6.6% decrease). 

The grand total of import from January to November was 36,523.3 tons, 8.9% increase comparing to same period of previous year, reflecting steady contribution of magnesium metal category.


The magnesium export in November consisted of 0 kg of pure magnesium, 14.0 tons of magnesium alloys, 18.6% increase on month-to-month basis (82.4% decrease). Magnesium powder was sleeping at only 31 kgs. Other products was 3.6 tons, 3.7% increase on month-to-month basis (72.0% decrease) including 0.5 tons and 3.0 tons to China and Vietnam respectively. The grand total export was 17.7 tons, 15.2% decrease on month-to-month basis (81.9% decrease).

As for the total amount of export from January to November, pure magnesium metal was 106.1 tons (12 fold increase from same period of previous year), magnesium alloy metal was 118.8 tons (74.7% decrease), magnesium powder was 12.7 tons (33.1% increase) and other products was 29.4 tons (30.5% decrease).
