You must pay careful attention to grain or rolling direction when bending high strength metals especially when trying to achieve a small inside bend radius.
Bending aluminum sheet with the grain.
In high purity forms aluminum is soft and ductile.
Bending sheet metal can be useful if it s used to build different shapes and different products.
The harder and thicker the metal the greater the minimum bend radius.
Which aluminum alloy bends the best is a a common question customers want the answer to.
This is because sharper or tighter bends can be made across the grain without cracking.
Local sheet metal shop not an aircraft shop experienced cracking on folding up a simple bracket.
Has anybody heard of bending sheet stock 063 5052 h32 aluminum with grain direction on the diagonal.
Grain direction also plays into the amount of springback you can expect.
A metal s grain direction is usually only a factor when bending however.
In this post we ll explain it to you.
Bending with the grain gives a different result than bending against it.
Bending the sheet metal longitudinally with the grain allows those grains to separate at the grain boundaries.
Bending is a delicate and demanding process most of the time and common fabricating processes require a degree of formability that make your choice of proper alloy critical.
In particular we will take an in depth look at the theory making a.
This will give you a nice bend.
Minimum inside bend radius is also larger when bending with the grain longitudinal than across the grain transverse.
Understand different metals have different minimum bend radius to thickness ratios.
To predict the material s behavior accurately during bending especially at the press brake you need to accommodate for the grain direction.
Against the grain if you bend with the grain it will split the grains ask login.
In this episode we are going to be looking at bending aluminum sheet metal for aircraft.
In addition the grain direction needs to be considered when the bend radius is less than twice the thickness depending on the material and its hardness.
