In order to find out what is highly reflective, it is important to know what the metal consists. Metals like Aluminum and Silver (reflects 95% visible light) are highly reflective and are used in the making of sun glasses, windows Nikola Kalinic Jersey , solar mirrors and jewelry. Reflective metals like gold, bronze, copper and brass are also hard to laser cut using CO2 lasers. Stainless Steel is also considered to be a reflective metal especially when an object made of steel is given a mirror polish. As the mirror finish makes it difficult to cut steel, it is coated with plastic on the cutting side to lessen the risk.

Why is it difficult to laser cut reflective materials?

As CO2 laser cutting technology makes use of light beams and mirrors for cutting Niccolo Zanellato Jersey , it becomes difficult to cut reflective metals. If you cut a material like aluminum using a laser machine, the laser beam gets reflected from the metal sheet back to the laser lens causing damage to the laser spare parts. If one is using branded machines like Precitec laser cutting machine, it can incur a damage of thousands of dollars as the laser delivery system might have to undergo a prolonged repairing process and maintenance including replacement of precitec laser spare parts.

Even if you cover the sheet with a non-reflective coating, it doesn’t always work as the surface of the metal is not the only source that reflects light. During laser cutting Matteo Gabbia Jersey , heat is generated and a molten metal is released from the laser which reflects and causes damage to the beam. This is the reason why several laser companies suggest an alternate method like Waterjet cutting to cut reflective metals. However, Waterjet method shouldn’t be considered as an only option for cutting reflective metals.

So how do you cut reflective metals?

Despite the risk of reflected beam damaging the laser machines, it is possible to laser cut these materials. But for that you need to take certain measures and follow some parameters. Usually, the modern laser machines come with a failsafe so that there is no damage to the equipment. Detectors of the laser head can identify the radiation levels and shut themselves off if a lot of radiation is reflected into the lens. So if the laser and the reflective sheet are set up properly and the job is done slowly and smoothly Mateo Musacchio Jersey , it is possible to cut reflective metals.

Fiber laser technology

Fiber lasers are the most modern, swift and cost effective way to cut thin reflective metal sheets. As these lasers do not use mirrors and delicate lenses, the reflection from metals like copper, aluminum and brass do not damage the cutting equipment making it quick and safe to set up. So Fiber laser technology is the best way to cut reflective metals.

What Makes Waterjet Cutting a better option?

The only drawback of Fiber Laser Technology is that it can be used effectively only on the sheets that are upto 5mm thick. If the thickness of sheet is more than that Marco Storari Jersey , it affects the cutting speed and shape of the cut. This is when Waterjet cutting can come of help. Waterjet cutting cut materials with thicknesses of up to 230mm which makes it even better than the widely accepted CO2 laser cutting technology.

Now that you know how to deal with reflective metals, you can take up this task with ease. All the best!


CHONGQING, July 6 (Xinhua) -- The former headquarters of the Allied Forces in China during World War II has received more visitors as China marks the 80th anniversary of the beginning of the war against Japanese aggression.


The number of visitors has risen from 290,000 in 2015 to 320 Manuel Locatelli Jersey ,000 in 2016, said Liu Wanhong, curator of the Chongqing Anti-Japanese War Heritage Museum. The first five months of this year has seen 140,000 visitors.


After the Pearl Harbor event in December 1941 Lucas Biglia Jersey , U.S. President Franklin D. Roosevelt decided to establish the China Theater Command of Allied Forces and named Chinese leader Chiang Kai-shek supreme commander and general Joseph Stilwell chief of staff.


Japan started a full-scale invasion into China on July 7, 1937. The ruling Kuomintang government led by Chiang evacuated to the southwest city of Chongqing at the end of 1937 after its capital Nanjing was seized by the Japanese. Chongqing then became China's temporary capital in wartime.


Chiang set up the headquarters of the Allied Forces on Huangshan mountain in the suburbs of Chongqing, where he and generals and consultants from the United States and the United Kingdom held hundreds of meetings to direct the war before it ended in 1945.


"China is a major battle field of World War II," said 84-year-old visitor Xie Yingwei. "We sacrificed a lot of people and will forever remember the war and the dead Luca Antonelli Jersey , to achieve a lasting peace."


According to curator Liu, visitors to Huangshan include delegations from U.S. Congress and former Flying Tiger pilots -- voluntary soldiers to aid China led by general Claire Lee Chennault, as well as Kuomintang officials from Taiwan.


The Chinese government has poured millions of yuan over the past years to preserve and renovate the 190,000-square-meter historical site Leonardo Bonucci Jersey , which is comprised of dozens of buildings and shelters on the forest-covered mountain.


The site was named a base for cross-strait exchanges between the Chinese mai.
